Dear support @till I renewed the SSL certificate today with no issues by using GeoTrust that I always use on one of the ISPConfig but now after restarting the server, I get an error status below...

No panic. Sorted. I found that one of the .key for the SSL files was not included in the /etc/pki/tls/certs/ which provides dovecot certificates. Also updated the .pem CA file. Thank you
