The issue occurs when a .key file has been removed from the user's ssl/keys/ folder, but remains in the user's SSL database. Rebuilding the SSL database will remove the missing file's entry from the user's SSL database.

Workaround

1. Access the server's command line as the 'root' user via SSH or "Terminal" in WHM.
2. Run the following command.

   /usr/local/cpanel/scripts/rebuilduserssldb $userrname

   Please note that "$username" must be replaced with the cPanel user's username.
