Description
The error typically happens when the server has intermittent connection issues to cPanel's licensing servers.
Workaround
You can check to see if the licensing port is open or the port is filtered on your server. To do this, run the command:
iptables -L -n | grep 2089
If the command returns the following:
ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 ctstate NEW tcp dpt:2089
Then the issue is a networking issue that needs to be investigated further by your server administrator. Networking issues are not something that cPanel Support can assist with as it may be from a higher level than your server, for example, the router or modem.
If you need the assistance of a server administrator, you can refer to the following article:
