IronPort C100V Alert - ESA cannot communicate with the update server

[haleaustria]

I get the following message every one hour and ESA won't get any updates: 

The updater has been unable to communicate with the update server for at least 1h

 Does anybody know a solution?

Other notes I collected from Forum :

ESA - Login using SSH - on the  CLI  run "showlicense", there's an email that the license is tied to.
The Cisco TAC automated agent, Sherlock Holmes, should have sent you a new set of license files.
If it didn't, or that email isn't available anymore, you'll have to open a TAC case.
