First, make sure that our license server is "seeing" the correct IP address. Run the following command at the shell command prompt:
The output will be an IP address. Copy that IP address and paste it into the box on License Verification - cPanel Inc., and click "Verify." If the output shows that the IP address has a trial license, please contact customer service at email@example.com for further assistance.
# curl http://www1.cpanel.net/apps/myip/
If our license server is seeing the correct IP address, and the verification page I mentioned above does not say the IP address has a trial license, please submit a ticket so that we may investigate the problem directly. You can submit a ticket at https://tickets.cpanel.net/submit/.
