The ERR_TUNNEL_CONNECTION FAILED error in the Chrome browser typically occurs on computer systems using a VPN or proxy server to connect to the internet. The following steps will help you resolve the Err_TUNNEL_CONNECTION FAILED error in Chrome on a home computer running Windows Home.
Tunnel connection error in Chrome
VPN or Proxy servers try to protect or hide your identity by removing header information from consumer requests to access websites. Most of the time this does not cause any problems and you will be able to connect to websites without any problems.
However, there is often a discrepancy between the expected and provided information, which results in the Tunnel Connection Failed error in the Chrome browser.
In simple terms, the ERR_TUNNEL_CONNECTION_FAILED error in Chrome can be described as an occasional inability of the Chrome browser to resolve VPN or Proxy connections on a Windows home computer.
How to fix the “Tunnel connection failed” error?
The easiest way to fix the tunnel connection error in Chrome may be to disable the proxy server on your computer and reload the web page you just tried to access.
However, if you still want to use VPN server or Proxy to connect to the net, you can try the following 2~5 strategies to fix Err_Tunnel_Connection_Failed error in Chrome.
1. Disable the proxy server
As we have already said, this answer is suitable if you want to connect to the net immediately and do not want to use VPN or Proxy connections.
Click on the 3 dots in Chrome, the menu icon in the top right corner of your screen, and click on Settings in the drop-down menu.
On the Settings screen, scroll to the bottom of the net page and click Start.
Scroll down to the "System" section and click on Open proxy settings.
On the Internet Properties screen, click on LAN settings located on the Connections tab.
On the LAN Settings screen, uncheck the Use a proxy server for purple native option and further examine the Detect parameters routinely option and click OK.
Restart your computer and you will be able to access the web page without the tunnel connection error appearing in the Chrome browser.
2. Test the proxy IP address, password and port
If you want to continue using Proxy connections, the first step is to check that you are using the correct IP, password and port for your computer's Internet Proxy connection.
Also make sure you use the correct username and password.
To check the IP sort out, try accessing another website using a proxy server. If you can access the other website, the IP sort out is correct.
Most proxies use port 80, but some proxy providers may use different ports.
The person's title/password must be recognized by you.
3. Disable routine detection settings
When the browser is going to mechanically detect the proxy settings, it follows the settings described in the working system.
In the case of home computers running Windows Home, the proxy settings may be better optimized for the Internet Explorer or Edge browser and never for the Google Chrome browser.
By disabling the option to detect settings mechanically, you can allow the Chrome browser to use its own settings or to use settings set by the proxy owner.
Click on the 3 dots in the Chrome menu icon > Settings.
On the Settings screen, scroll to the bottom and click Start.
Scroll down and click on the Open proxy settings option located in the "System" section.
On the next screen, press the Links button (if you're not already there) and click the LAN Settings button.
On the native area purple settings screen, uncheck the Detect routine settings option and click OK.
Restart your PC and check if the tunnel connection error still appears in the Chrome browser.
4. Reset TCP/IP and clear DNS
Click correctly on the Home button > Immediate Commander (Admin)
In the command prompt window , type the following commands one after the other (in the same order) and press Enter after each command.
- netsh winsock reset
- netsh int ip reset
- ipconfig /launch
- ipconfig /renew
- ipconfig / flushdns
- ipconfig / registerdns
Now, restart your computer for the changes to take effect and check if the Tunnel Connection Error Failed error still appears in the Chrome browser.
5. Contact your representation service provider for assistance
If you still can't fix the problem, go to your proxy provider's website and submit a support request. If you have a large service provider, you can count on them to have knowledgeable support staff who can help you troubleshoot the error.
