Proxied site not available using Serverpilot, Let's Encrypt, and Cloudflare

I have a site using Serverpilot with SSL enabled using their AutoSSL. The site works fine and is accessible via https when Cloudflare is disabled (grey cloud). However when enabling Cloudflare, the site is not accessible, and I see a page with the following error:

Firefox
Secure Connection Failed
Error code: SSL_ERROR_NO_CYPHER_OVERLAP

Chrome
This site can’t provide a secure connection
ERR_SSL_VERSION_OR_CIPHER_MISMATCH

If tried toggling the SSL settings between off/flexible/full but that hasn’t helped.

Thanks

Search for these error codes here. The certificate on the proxied wont have issued yet. The articles you will find will also tell you what to do in this case.

Whats the domain?

Thanks @sandro

I’ve been reading the forums and cant find a solution. Most people seem to toggle SSL from flexible/full, but that hasn’t worked for me.

Thanks

You dont change your encryption mode (which should always be Full Strict), you should toggle Universal SSL altogether and wait 30 minutes inbetween.
