March 28th 2026: Unable to activate cPanel license, Updating cPanel license...Done. Update Failed! Print

  • 0

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.
