Check cPanel Licence Verification

How to check cPanel Licence Verification? 

To verify the licence of the cPanel

 open this link http://verify.cpanel.net/.

If the licence is valid then login as root to the server and run the following to refresh the license.

If this command errors or you do not see the server contacting cPanel license servers to verify your license, please check that your server is able to contact servers via port 80 (so, check your firewall’s OUTPUT options) and that you have a proper hostname set on your server. cPanel makes the connection to one of the cPanel licensing servers through port 2089. So we should make sure that this port is open.
