SSL errors take down site when using CloudFlare nameservers

Hi all,

I’ve just updated my DreamHost nameservers to a Cloudflare free tier… and suddenly my website is inaccessible!

Firefox: SSL_ERROR_NO_CYPHER_OVERLAP, Chrome: ERR_SSL_VERSION_OR_CIPHER_MISMATCH

When I search these two error codes, the previous posts in this forum seem to indicate they were caused by temporary service outages, but I see no relevant outages at https://www.cloudflarestatus.com/

What is the domain?

Thank you for the quick replies.

I resolved my issue, which was that my Cloudflare SSL/TLS encryption mode was erroneously set to “Flexible”.

From the Cloudflare dashboard, going to Websites > [my site] > SSL/TLS and changing SSL/TLS encryption mode to “Full (strict)” resolved the issue.
