CONFIG_TEXT: ==> cpsrvd: loading security policy....Done
==> cpsrvd: Setting up SSL support ... Failed to load SSL libraries or certificate from /var/cpanel/ssl/cpanel/ at cpsrvd.pl line 697.

Cause

The cPanel service has failed due to the file located at /var/cpanel/ssl/cpanel/mycpanel.pem being empty and needs to be moved.

Resolution

Move the empty file and restart the cPanel service.

1. Log in to the cPanel and WHM server as the root user via SSH.
2. Run the following command.

# mv /var/cpanel/ssl/cpanel/mycpanel.pem{,.$( date +%Y%m%d )} -v

# /scripts/restartsrv_cpsrvd
