4. Disable proxy and use a VPN instead

If everything else fails, consider dropping your proxy server and using a reliable VPN instead. If you encounter a Chrome update error, check if the Google Update service is enabled on your PC. If you have proxy connection issues on Windows 10, you might have to perform a malware scan on your computer and remove any suspicious software applications which may be the cause of the proxy err_tunnel_connection_failed error. Once you determine that the error solely occurs in Chrome, make sure to clear browsing data and cache. Afterward, restart the web browser and try again. We suggested Private Internet Access (PIA) in our example above because it’s the best VPN for secure browsing. Besides protecting your online privacy, PIA can also unblock websites and help you watch Netflix US, Hulu, and others. Created by Kape Technologies, Private Internet Access brings more than 3,300 VPN servers spread across 48 countries. It’s compatible with Windows, Mac, Linux, Android, iOS, and even routers. Plus, it has browser add-ons prepared for Google Chrome, Mozilla Firefox, and Opera. If you still want to use a proxy server, you can do so while the VPN connection is active, thanks to the fact that PIA has built-in SOCKS5 and Shadowsocks proxy. It also includes exclusive DNS servers, an ad and malware blocker for browsers, an emergency kill switch, together with static and dynamic IP addresses. More about PIA:

We suggest using Google Public DNS, Cloudflare, or OpenDNS since they are public, free, fast, and secure DNS servers. It’s the same thing as installing a fresh version of Chrome on your PC, which is unaffected by user settings and various ways of customization.
