Try disabling scanning of HTTP/HTTPS traffic and SSL certificates. If antivirus detects that the website is using an insecure (or self-signed) certificate or a legacy SSL protocol version (SSL 3.0 or TLS 1.0), the antivirus may block the user’s access to such a site. To understand if your antivirus or firewall blocks access to a site, try to pause them for a while.Ī lot of anti-viruses have a built-in module that checks the SSL/TLS certificates of websites. If you have an antivirus or a firewall (it is often built into the antivirus as a module) installed on your computer, they may block access to websites. You can view the list of enabled Chrome extensions in Settings -> More Tools -> Extensions or go to chrome://extensions/. We recommend to disable (delete) third-party browser extensions, especially anonymizers, proxies, VPNs, antivirus extensions, and other similar add-ons that can interfere with traffic to the target website. Restart your browser and check if the error ERR_SSL_PROTOCOL_ERROR persists.The message “ The SSL cache was successfully cleared” will appear.Go to Control Panel -> Internet Options.In Chrome, press Ctrl + Shift + Delete (or go to the address chrome://settings/clearBrowserData), select the time range ( All time) and click Clear data. We recommend to clear cache and cookies in your browser first. Clear Browser Cache, Cookies, and Reset SSL Cacheīrowser cache and cookies often cause an SSL certificate issues.
Also check if you can open a problem website in other browsers: IE/Edge or Mozilla Firefox. Try to open from other devices (smartphone, tablet, home/work PC, etc.). I would like to note that despite Google Chrome, Opera, and Chromium-based browsers being released by different companies, they are using the same WebKit ( Chromium) engine, and the problem of opening HTTPS sites is solved in the same way for all of them.įirst of all, make sure that it is not the problem of the HTTPS website itself.
