Community Tip - Fixing ERR SSL VERSION OR CIPHER MISMATCH in Google Chrome

Error Try the suggestions in this Community Tip to help you fix ERR SSL VERSION OR CIPHER MISMATCH in Chrome. Background A website using HTTPS performs a series of steps between the browser and the web server to ensure the certificate and SSL/TLS connection is valid. These include a TLS handshake, the certificate being checked against the certificate authority, and decryption of the certificate.

Please dont do it this way. You shall just start migrating to Cloudflare once your setup is secure, properly setup and working. So please fix your SSL Error without Cloudflare and after this migrate to Cloudflare.

Your Host does not let you install the origin SSL Cert from Cloudflare. So your host is blocking you by doing this and therefor your host should not refer to Cloudflare. They block this because Cloudflare is not a recognized SSL vendor and therefore they do not let you install this SSL cert.

Also their Error message is wrong, as this certificate is for your domain name. The vendor is just not a publicly recognized vendor. Thats all.

Referring to THIS there is not workaround to install Cloudflares origin SSL Cert.

But to solve the problem please install a Lets Encrypt SSL Cert and then switch to SSL Mode “Full Strict”. That should do the trick.

To do so you probably have to bypass Cloudflare and set it temporary into “Development Mode”.
