I keep getting the “ERR_TUNNEL_CONNECTION_FAILED” error when trying to browse certain websites. What usually causes this, and what steps can I take to resolve it quickly?

This is almost invariably the result of improperly configured proxies or VPNs, and disabling them, reconfiguring network-related settings, verifying the firewall permissions, and making sure the connection is stable will fix a problem in just a matter of minutes.

Check your proxy settings and disable any incorrect proxy. Clear cache, restart Chrome, and ensure your internet connection is stable. Disable VPN temporarily, update Chrome, or reset browser settings if the issue continues.
