Check VPN and Proxy Settings (Disable them if required)<\/h3>\n\n\n\n<p class=\"justify\">Since proxy server issues are generally the main cause of the error, simply adjusting your Operating System&#8217;s settings to automatically find proxy settings or set it to use a specific server would fix the issue.<\/p>\n\n\n\n<p class=\"justify\">These proxies and VPNs act as intermediaries between your computer and the internet and provide privacy as well as bypass geo-restrictions.<\/p>\n\n\n\n<p class=\"justify\">If you have misconfigured proxy settings it can block Chrome from making a secure connection and hence lead to this issue. Also, an unresponsive proxy server can cause the same.<\/p>\n\n\n\n<p class=\"justify\">When talking about VPN, it generally changes your IP address and routes your traffic through different servers. This can trigger problems if the VPN servers are not optimized for your location or the websites you visit.<\/p>\n\n\n\n<p class=\"justify\">To fix this, all you can do is ensure the settings are properly configured or is possible disable them directly.
