Strong cipher suits for plesk interface

Hi,

I want to aloow only strong cipher suits for everything that uses TLS I have a few pages which all use these strong ciphers, but plesk does not adapt to this. domain.tld is fine, but domain.tld:8443 still uses "weaker" cipherSuits.
I already put in the /etc/apache2/mods-available/ssl.conf the following lines:
SSLCipherSuite EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH
SSLHonorCipherOrder on
SSLProtocol -all +TLSv1 +TLSv1.1 +TLSv1.2

This did not affect any cipher suits, but...
