Problem #

The system is not successfully syncing IP addresses for licenses that you provision and manage using the cPanel Licensing addon module.

Cause #

You have not correctly configured the necessary custom fields in WHMCS.

The cPanel Licensing addon module sets license IP addresses by checking for a Dedicated IP or IP Address custom field. These custom fields might not exist, or you may have renamed them, causing the system to be unable to find them.

Solution #

To resolve this issue, go to Configuration () > System Settings > Custom Fields. Ensure that a Dedicated IP or IP Address custom field exists and that the field uses the correct name.
