If you’re experiencing the frustrating “Webpage Not Available” error in Google Chrome, particularly with the ERR_TUNNEL_CONNECTION_FAILED message, you’re not alone. This guide will walk you through comprehensive troubleshooting steps to restore your internet access and enjoy seamless browsing again. Whether you’re using Windows 11, Windows 10, or any compatible PC setup, the solutions provided here will help you tackle common connectivity problems, including DNS and network issues. Read on to discover effective fixes and enhance your browsing experience.
Step 1: Check Your Internet Connection
The first step in resolving any connectivity issue is to confirm that your internet connection is stable. Start by connecting other devices to the same network to check if they can access the internet. If other devices also cannot connect, the problem may lie with your internet service provider. Restart your modem or router to refresh the connection. If the issue persists, consider contacting your ISP for assistance.
Step 2: Disable Proxy Settings
Sometimes, proxy settings can interfere with your internet access. To disable them, follow these steps:
- Open the Settings app on your computer.
- Navigate to Network & Internet and select Proxy.
- In the Proxy settings, ensure that the option for “Use a proxy server” is turned off. If using automatic settings, check if they are configured correctly.
Disabling proxy settings can often resolve the ERR_TUNNEL_CONNECTION_FAILED error, as Chrome may be trying to access the internet through a misconfigured proxy server.
Step 3: Flush DNS Cache
Flushing the DNS cache can resolve various browsing issues, including the “Webpage Not Available” error. Here’s how to do it:
- Search for Command Prompt in the Windows search bar, right-click it, and select Run as administrator.
- In the Command Prompt window, type
ipconfig /flushdnsand hit Enter.
Once the DNS cache is flushed, reconnect to your network and check if the error persists.
Step 4: Change DNS Server Settings
Switching to a public DNS server can improve connectivity and potentially fix the ERR_TUNNEL_CONNECTION_FAILED issue. To change your DNS settings:
- Open the Control Panel and navigate to Network and Sharing Center.
- Select Change adapter settings.
- Right-click your active network connection and choose Properties.
- Highlight Internet Protocol Version 4 (TCP/IPv4) and click on Properties.
- Select Use the following DNS server addresses and input:
- Preferred DNS server: 8.8.8.8
- Alternate DNS server: 8.8.4.4
This change should improve your browsing performance and may resolve the error.
Additional Tips & Common Issues
While following these steps, keep in mind the following tips:
- Make sure your Google Chrome is updated to the latest version.
- Try disabling any VPN or security software temporarily, as they may affect your connection.
- If issues persist, consider resetting your network settings entirely as a last resort. This can be done through Settings > Network & Internet > Status > Network Reset.
Conclusion
In conclusion, encountering the “Webpage Not Available” error with the ERR_TUNNEL_CONNECTION_FAILED message can be quite annoying, but with the troubleshooting steps outlined above, you should be able to resolve the issue effectively. Maintaining a stable internet connection and adjusting your network settings can significantly enhance your browsing experience.
