If you are experiencing a “Tunnel connection failed,” you might want to check if there is an antiviral program running or installed on the PC. Also, clear your browser’s cache. Reset TCP/IP settings, change to Google Public DNS, and try again. You might also want to consider changing your proxy settings.

Here we’ll show you how to fix the “tunnel connection failed” or “ERR_TUNNLE_CONNECTION_Failed” errors in Google Chrome.

Why is the tunnel connection failed error occurring?

When you are trying to connect to a site via VPN, you might come across an error like “Tunnel connection failed.” If you encounter this error while connecting to a VPN server, here are some possible reasons why you are getting such an error.

1. You are behind a firewall. In this case, you cannot use the tunneling protocol because the firewall does not allow connections over port 443.

2. Your router doesn’t support PPTP. If your router supports PPTP, make sure that the router is set up correctly.

3. A third-party software is blocking the traffic. Make sure that the software isn’t interfering with the process.

4. You are connecting to the wrong IP address. Make sure that you entered the correct IP address.

5. There could be a network issue. Check the status of your internet connection.

6. You don’t have enough bandwidth. Try increasing the speed of your internet connection. Also, check whether your modem/router supports PPPoE or PPPoA.

How to eliminate err tunnel connection failed error?

Make sure your browsing data is cleared

Google Chrome has a settings feature called “Settings.” This feature allows you to access different options related to the browser itself. There are many features under the Privacy & Security category. One such setting is clearing browsing data.

If you don’t see the settings option, it could mean you’re running the latest version of the browser. If you don’t see anything there, you might have an older version of the browser installed on your computer. To update to the newest version, follow the steps mentioned below.

1. Click the icon in the upper left corner of the browser. From there, select Settings.

2. From there, scroll down to the Privacy & Security section and click the Clear Browsing Data option.

3. A new window will pop up where you’ll find a link to clear your browsing history, cookies, cache, etc. Click the OK button to proceed.

4. You’ve cleared your browsing data now.



The proxy server should be disabled

Companies use proxy servers to restrict access to certain websites, block ads and prevent people from accessing certain information. If you use a proxy server, it could potentially slow down your internet connection and make browsing the web slower. You might even find yourself blocked from some sites altogether.

If you want to disable the proxy server, follow the steps below:

1. Open the Network Settings window by clicking on the network icon located next to the clock on your desktop.

2, Click on the Advanced tab.

3, Scroll down and select Proxies.

4. Uncheck the box next to Enable proxy server.

5. You can now enjoy unrestricted surfing without any restrictions.

Flush DNS and reset TCP/IP

1. Press the Win+R keys together to open the Run dialog box. Type cmd into the text field and press Enter key to launch Command Prompt window.
