    Hi,

    I disabled TLS versions 1.0 and 1.1 and put the SSL settings to modern on my plesk server but cdn77.com tls test shows them still enabled. Also the nmap test shows them.
    I run Plesk Obsidian 18.0.27 Update #1 on Centos 7.

    Output of 

    ]# cat /etc/sw-cp-server/conf.d/ssl.conf
    ssl_protocols TLSv1.2;
    ssl_ciphers EECDH+AESGCM+AES128:EECDH+AESGCM+AES256:EECDH+CHACHA20:EDH+AESGCM+AES128:EDH+AESGCM+AES256:EDH+CHACHA20:EECDH+SHA256+AES128:EECDH+SHA384+AES256:EDH+SHA256+AES128:EDH+SHA256+AES256:EECDH+SHA1+AES128:EECDH+SHA1+AES256:EDH+SHA1+AES128:EDH+SHA1+AES256:EECDH+HIGH:EDH+HIGH:AESGCM+AES128:AESGCM+AES256:CHACHA20:SHA256+AES128:SHA256+AES256:SHA1+AES128:SHA1+AES256:HIGH:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!3DES:!MD5:!PSK:!KRB5:!aECDH;
    ssl_prefer_server_ciphers on;

     

    What do I miss?
