I have 2 sites, setup completely the same way, but 1 is bugging in only a specific scenari. I have setup certbot certificates, the SSL/TLS certificates is in Full mode, and the www. version of the sites are setup as CNAMEs to their non-www versions.
One of the sites is subdomain of the other.
For the second site there is issue in only one scenario. All of the following work fine:
But, but, when i visit:
https://www.blog.site.geo.tld I am presented with the following error:
Firefox: Error code: SSL_ERROR_NO_CYPHER_OVERLAP
Chrome: ERR_SSL_VERSION_OR_CIPHER_MISMATCH (uses an unsupported protocol)
I have no idea why this might me happening, since the 2 sites are setup identically. Would someone happen to have even a slight idea, what may be causing this behavior?
