One of the errors you can encounter while browsing the web using your Google Chrome browser is the ERR_TUNNEL_CONNECTION_FAILED error. If you happen to encounter this error, then this post could help you resolve it. This kind of error in Chrome can occur due to incorrect website domain configuration, conflicting browser data, incorrect proxy settings, and DNS connection issues.

To resolve the ERR_TUNNEL_CONNECTION_FAILED error in Chrome, here are some suggestions you can check out.

Option 1 – Try disabling the proxy server for your LAN

If your PC was just attacked by some adware or malware as of late, it is possible that it has changed the network settings in the system and might display spam advertisements. Thus, you have to disable the proxy server for your LAN. To do that, refer to these steps:

  • Tap the Win + R keys to open the Run dialog box.
  • Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
  • After that, go to the Connections tab and select the LAN settings.
  • From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
  • Now click the OK and the Apply buttons.
  • Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.

Option 2 – Try to reset Winsock, TCP/IP & Flush DNS

Resetting Winsock, TCP/IP, and flushing DNS might help you resolve the ERR_TUNNEL_CONNECTION_FAILED error. To do so, follow these steps:

  • Right-click on the Start button and click on Command Prompt (administrator) so you can pull up an elevated Command Prompt.
  • After that, execute each one of the commands listed below. And after you typed in one after the other, you have to hit Enter.
  1. netsh winsock reset – type in this command to reset Winsock
  2. netsh int ip reset resettcpip.txt – type in this command to reset TCP/IP
  3. ipconfig /flushdns – type in this command to flush the DNS cache
  • Next, restart your PC and check if the problem’s fixed.

Option 3 – Try using a VPN connection

There are instances when the network that your computer is logged on might have blocked your access to the website you are trying to open and so to fix it, you can try to use a VPN connection. Once you’ve connected using VPN, try to open the website again and see if you can now access it.

Option 4 – Try clearing browser data

There are times when some data in the browser is conflicting with the loading of the website and triggers errors like ERR_TUNNEL_CONNECTION_FAILED. And so you can try to clear your browser’s data. This might be a very basic solution but oftentimes it works in fixing this kind of error in Google Chrome. Follow the steps below to clear the data in your browser.

  • Now select every checkbox that you see and click on the Clear browsing data button.
  • Then restart your Chrome browser and check if you can now open any website or not.

Option 5 – Get rid of any conflicting browser extensions

  • Open Chrome and press Alt + F keys.
  • Go to More tools and click Extensions to look for any suspicious browser extensions or toolbars.
  • Click the Recycle bin and select Remove.
  • Restart Chrome and press Alt + F keys again.
  • Proceed to On Startup and mark Open a specific page or set of pages.
  • To check if the browser hijacker is still active, click Set pages, if it is active, overwrite the URL.

  • Open Google Chrome, then tap the Alt + F keys.
  • After that, click on Settings.
  • Next, scroll down until you see the Advanced option, once you see it, click on it.

The new Windows 11 dev build will be buggy
windows 11 dev build channelMicrosoft sent an email to users on the Dev build channel saying that the company intends to push some builds that don’t represent what consumers will receive with Windows 11 when it officially releases. In other words, these are going to be some rather buggy builds that won’t be too enjoyable to use. The company recommends users switch from the Dev to the beta channel if they aren’t prepared to deal with the instability. We’ll have to wait and see just how buggy these builds are, but if Microsoft is actually sending out a warning about them it is very likely that builds will be plagued with issues and maybe even stability problems.

Back to Windows 10

How we can expect some buggy build of Windows 11 if you prefer a stable system over new features maybe best decision would be to switch back to Windows 10 until the new OS hits official release.

Switching from dev build channel to beta channel

Another solution, if you do not want to deal with too many issues, is to switch from Dev build channel to beta where things will be more stable. Follow the guide below in order to quickly switch to the beta channel. Following instructions only apply to Windows 11 installations that are linked up to the Windows Insider program, not clean installation of OS.
  1. Press ⊞ WINDOWS + I to open settings
  2. Inside settings click on Windows update
  3. In Windows Update click on Windows Insider Program
  4. Inside click on Choose your Insider Settings
  5. Click on the button next to Beta Channel to select it (you can switch back to the Dev channel here if you change your mind)
The setting will be saved automatically and from now on you will only receive beta channel updates.

Delete large System Error Reporting files
In case you don’t know, Windows contains a feedback mechanism that generates error reports from hardware and software problems. These reports are temporarily stored in the system and send them back to Microsoft so that it can find solutions to the reported problems and fix them in the upcoming updates.  However, as time goes by, these reports actually take a lot of space in your computer which is why end-users like you are free to delete them with the help of the new Free Up Space feature in Windows 10. As useful the Free Up Space feature may be, there are times when you won’t be able to use it for some reason which is why in this post, you will be guided on how to use alternative ways in deleting very large System queued Windows Error Reporting file, some of which may run in Gigabytes. Every time the Windows Error Reporting or WER sends out an error file and looks for a solution, the WER server at Microsoft sends out a solution instantly. And if the solution is under investigation or is unknown, then you will be notified about it right away and will be asked for more details. As mentioned, even though the Free Up Space feature in Settings will be able to clear the error reporting files, there are instances when it won’t be able to delete very large System queued Windows Error Reporting files. Alternatively, there is an option to delete these files using the Disk Cleanup Utility. Feel free to select which option you’d like to use to get rid of Windows Error Reporting Files.

Option 1 – Delete Windows Error Reporting Files via Settings

  • Go to Settings.
  • From there, go to System > Storage > Free Up Space and then click on it to launch it.
  • Afterward, give it some time to populate all the files and folders. Once it’s done, select “System created Windows Error Reporting files” to mark its checkbox while leaving the other options unchecked.
  • Next, click on the Remove files button to delete all the Windows Error Reporting files from your computer.

Option 2 – Manually delete the Windows Error Reporting Files

  • Tap the Win + E keys to open File Explorer.
  • Next, enable the Hidden Files view from the menu.
  • Then go to C:/ProgramData/MicrosoftWindowsWER.
  • From there, you will see various folders like LocalReportArchive, ReportArchive, ReportQueue, and Temp.
  • Open each one of the aforementioned folders and delete the archive files. Note that these files will have names similar to “00c58c1f-b836-4703-9bcf-c699ca24d285”.
Note: If you are not able to delete any of these files, you have to take ownership of the folder. To do so, refer to these steps:
  • Right-click on the folder and then select Properties.
  • Next, click on the Edit button in the Properties window and click OK to confirm if you got a User Account Control elevation request.
  • After that, select user/group from the permission windows or click on the Add button to add another user or group. It would be best if you add “Everyone” to give permission.
  • Then check “Full Control” under the “Allow” column to assign full access rights control permissions.
  • Now edit the permission to Full Control for “Everyone”.
  • Click OK to save the changes made and then exit.
On the other hand, if you do not want to go through all these troubles in deleting the Windows Error Reporting files, you can just disable it especially if it already becomes a daily annoyance as the files generate every day and their sizes are mostly gigabytes. And besides, there are times when these files do not make it to the Microsoft WER server and end up only occupying a lot of space for nothing.

YOU ARE NOT AUTHORIZED TO ACCESS ...
If you have encountered the “YOU ARE NOT AUTHORIZED TO ACCESS THIS WEB PAGE AS PER THE DOT COMPLIANCE” error while trying to visit a website using either Firefox or Chrome browser, then read on as this post will guide you on how you can fix this error. Apart from this error message, you might also see an alternative message that says, “Web Page Blocked! The page you have requested has been blocked because the URL is banned as per the Government Rules”. When you get any of the aforementioned error messages when visiting a website, this means that it has been marked. It is mostly recommended to not access the site as it might be blocked for some illegal reason. However, if you are certain that the website is legitimate and safe and you believe that it has been blocked by accident, then you can check out the given methods in this post to unblock and access the blocked or restricted website. There isn’t actually a straightforward way to remove the restriction on the website or the DOT compliance. And it won’t matter what browser you use as you will still get the same error. Thus, the best way to go about this issue is for you to bypass the ISP restriction. But before you proceed, keep in mind that the ISPs (Internet Service Providers) can block any website when a request goes through their servers.

Option 1 – Try changing the DNS

If the request to access the website does not go through the ISP’s DNS server, you might have a chance in accessing it by changing your DNS settings. You can try using the Google Public DNS.
  • Tap the Win + R keys to open the Run dialog box.
  • Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
  • After that, go to the Connections tab and select the LAN settings.
  • From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
  • Now click the OK and the Apply buttons.
  • Restart your PC.
Note: If you are using a third-party proxy service, you have to disable it.

Option 2 – Try to install a Proxy Extension

You could also try installing a Proxy extension or Proxy software as it could also help you access the website you are trying to open as it allows you to access the blocked websites by routing the request through their server. Aside from that, it can also hide it from ISPs to make them look like the content is coming from the proxy servers.

Option 3 – Try using a VPN connection

There are instances when the network that your computer is logged on might have blocked your access to the website you are trying to open and so to fix it, you can try to use a VPN connection. There is a lot of free VPN software out there but just make sure that you install a trusted one. Once you’ve connected using VPN, try to open the website again and see if you can now access it.

Option 4 – Check the Windows Host file

You can also try to cross check the Windows Hosts file to find out if the website you are trying to open has been blocked because if it is, then it’s no wonder why you’re getting the ERR CONNECTION TIMED OUT error in Chrome. There are instances when some third party application modifies the file and add some websites to the block lists. So if the website is indeed blocked, you need to remove it from the list.

Option 5 – Try to contact your ISP

If none of the options given above worked, then you can try to contact your ISP as there are times when DOT clears a website, the ISPs are still blocking it. Thus, it’s probably better if you reach out to them and ask them to unblock the website from their end.

Fix Something went wrong with the projection
As you know, Windows 10 is created with the goal of developing an operating system that caters to users’ needs and enhances productivity. That’s why modern computers that are running the Windows 10 OS have the capabilities to project their screen to an external display wirelessly. That said, Microsoft has a dedicated and pre-installed app called Connect which helps another device to project their screen on the computer. However, this feature is kind of delicate and won’t work unless it’s properly configured. So if some configuration does not work out well, it will throw an error message that says
“Something went wrong with the projection”.
This kind of error is caused by some issues with the Display driver, hardware, corrupted or damaged system files, and so on. And to fix it, there are several methods you can check out. You can try to update, roll back or reinstall the Display drivers. You could also run the Network Adapter troubleshooter or the Video Playback troubleshooter as well as run System Restore to undo any recent changes that might have triggered the error or reset your Windows 10 computer without deleting any files.

To run it, simply go to Settings > Update & security > Troubleshoot. From there, scroll down until you see the Video Playback option and then click on the “Run the troubleshooter” button to get started. This troubleshooter will detect and automatically fix any problems related to video playback so it should help fix the error.

Option 4 – Try performing a System Restore

Drive letter missing in Windows File Explorer
There are times when you might notice that the Drive letter from the File Explorer is missing, right after you install an update in your Windows 10 computer. So if you are facing this issue right now, then you’ve come to the right place as this post will guide you on what to do to fix it. In case you don’t know, a drive letter represents a single alphabetic character which is through A-Z typically. This could be assigned to a physical disk partition, floppy disk drive or the removal device/ CD-ROM/ mapping network drive in your PC. In most cases, the drive letter “C:” is assigned to the first disk partition where the running Windows is installed. Thus, if the assigned letter is missing from either the Disk Management or the Windows File Explorer, it could result in inconveniences or will leave the partition inaccessible. To fix this problem, you can try to show the missing drive letters manually or make sure that the drive has a drive letter assigned in the Disk Management as well as assign the letter using a tweak in the Windows Registry. For more details, refer to the options provided below.

Option 1 – Try to show the missing drive letters manually

  • Open the Folder Options from the Start Search and go to the View tab,
  • Next, scroll down on the list of given options until you see the “Show drive letters” option and then check the box that’s marked against this option.
  • After that, click on the Apply and OK buttons and then go back to the “This PC” window. You should now see the drive letters

Option 2 – Make sure that the drive has a drive letter assigned in Disk Management

As you know, every drive is assigned a drive letter in Disk Management. However, if it goes missing, you can still get it back through Disk Management. To do so, follow the steps below.
  • Open Disk Management and from there, right-click on the menu of a partition or volume and you should see a function named “Change Drive Letter and Paths”.
Note: This function allows you to add the drive letter, remove the drive letter and change the drive letter. If the last option, namely, “Remove”, is selected and applied, the letter of the drive will be removed and won’t appear in Disk Management. Thus, this could be one of the reasons why a drive letter is missing.
  • You need to click on “Add” to assign a letter to the selected drive in order to reverse the change. Note that you must assign the drive with the original letter because if not, the programs that rely on the original letter might not work as expected.
  • If the original letter is already taken by a new drive, you need to change the letter of that new drive to another available letter.
  • Then allocate the released letter of the targeted drive.

Option 3 – Try assigning the letter using a Registry tweak

The next thing you can do to fix the problem is to assign the letter using a tweak in the Windows Registry but before you do that, make sure that you create a System Restore point first, after that, follow these steps:
  • Tap the Win + R keys to open Run and type “Regedit” in the field and then tap Enter to open the Registry Editor.
  • Next, navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMMountedDevices
  • From there, check if a device is shown as being mounted at the specific drive letter and then right-click on that drive letter.
  • Select the “Rename” option from the right-click menu to change the letter to any other available letter.
  • Exit the Registry Editor and restart your computer.

Option 4 – Try to format the destination drive

Formatting the drive can also help you resolve the error. To format it, follow these steps:
  • To get started formatting your drive, tap the Win + E keys and then go to the access page of the drive.
  • Next, right-click on the drive and select Format.
  • After that, uncheck the “Quick Format” option and then format your drive properly.
  • Now once the formatting process is finished, unplug the drive and plug it back in afterward.
  • Check if the error is already fixed. If the drive is not initialized, tap the Win + R keys and hit Enter.
  • After opening the Run dialog box, type “diskmgmt.msc” and hit Enter to open Disk Management.
  • From there, right-click on the drive volume and select initialize disk.
  • Next, select the correct partition type and proceed.

After determining the cause then you can now start fixing the error. Check if Hardware is functioning properly. If the cause is due to a hardware malfunction, you will have to make sure that all the pieces you are using are working. All the wires should be attached to their respective ports. Not only that, but you also must make sure that before installing the hardware, it is compatible with the Windows version that is installed into your computer. Use Compatible software. If the problem was caused by software or a driver, you can uninstall and reinstall it. Always make it a rule that whenever you install a program or new software to your computer, make sure it is compatible with your operating system and never skip a step during the installation process. You also have to see to it that the program you are installing does not contain any viruses, malware, or spyware that can be harmful to your computer. Update your Drivers Regularly. In most cases though, the cause of the APC_INDEX_MISMATCH error are outdated device drivers. To resolve this, you will have to go to your Control Panel then look for Device Manager.

This enables you to send and receive emails. When you use Microsoft Outlook to send emails, your computer sends a message to the server computer in an obscure coding. The server responds to your computer with another message that contains the results of the executed program. This is all being carried at the backend of the running program. Integral to this is the endpoint. The endpoint includes the name, port, or a group of ports on a computer that is monitored by the server for incoming client requests. This is a network-specific address to be precise. The endpoint mapper is the part of the RPC subsystem that is responsible for dynamically assigning endpoints to the server.
