One of my websites has ERR_SSL_VERSION_OR_CIPHER_MISMATCH since 7 weeks when I enable Cloudflare (currently set to paused to keep it running). Before it was working fine as the other two sites on the same server.
Everything done from me and Hostinger support (DNS ok, new SSL certificate by their support, none, flexible and full tested, Disable Universal SSL and on, etc…).
Their advice:
Alright, I highly recommend reaching out to the Cloudflare team directly over the issue, so they could look into it from their end and provide more information as to why it is non-working once Cloudflare is enabled on the domain name. Thank you for understanding the matter
Thanks for help or advice!
