Your server needs to be able to communicate with the license servers. To confirm that your server's main IP address matches the IP address that is stored in cPanel's license servers, perform the following steps:

Run the following command as the root user:


If the IP addresses do not match, you will need to perform one of the following actions:

Change the routing in your server and network to route outbound traffic from the IP address that is licensed.

Change the IP address on the license to match the IP address returned by the curl command.

Check your license on to confirm that it is valid. If your license is not valid, contact your license provider.

If your license is valid, run the following commands as the root user:

rdate -s

Confirm that your server queries the root nameservers and has a valid hostname. If you need assistance with this, contact your hosting provider.

If these steps did not fix the issue, contact your license provider.
