Symptoms
When trying to activate the cPanel license, you are receiving a generic failure such as the one below:
/usr/local/cpanel/cpkeyclt
Updating cPanel license...Done. Update Failed!
Additionally, you've verified that your firewall and network is in compliance according to the article here:
What ports need to be open in the firewall for the cPanel license server?
Description
This should be resolved as of 12:30PM CDT -500. The auth.cpanel.net servers experienced an overloaded event leading to false failures being returned via the License check. We have modified automation on these servers to prevent this behavior moving forward.
