After the CWP updates you might deal with the following problem
None of your users can login to cpanel.
The error is the same "Login Failed".
The solution that usually works to this issue is the following
1st run the following commands
cd /scripts
sh generate_hostname_ssl
sh cwpsrv_rebuild_user_conf
2nd go to CWP panel to Server Settings --> Change Hostname and press Change Hostname and then run the following command
3d step is to restart the server and cpanel for user will be back working normally
