My website was running fine on HTTPS with LE-cert for weeks. Yesterday I tested Cloudflare and added their NS server at my domain hoster. Today I stopped using Cloudflare and deleted my website in my CF account and resetted the NS Servers to my old nameservers provided by my domain hoster. So far so good. Now I get this error when trying to access my website: SSL_ERROR_INTERNAL_ERROR_ALERT
I renewed the cert, but that didn’t help. Any idea?
