Every page of my WordPress site now throws an “ERR_SSL_VERSION_OR_CIPHER_MISMATCH” message instead of loading. No updates, migrations, or certificate renewals were done recently, so the problem appears to be server-side or within the current SSL/TLS configuration. I need you to trace the root cause quickly—whether it sits in the certificate chain, the web-server settings (Apache/Nginx), Cloudflare, .htaccess rules, or WordPress itself—then correct it so the site opens securely over HTTPS without any warnings. Once the fix is in place, please give me a concise summary of what you changed so I can keep future renewals or server tweaks problem-free.
