Cannot connect to the license server NoNetworkConnection -310

When i open Trados as an administrator i get an error that the license has expired.

When i try to activate with my license server i get a error saying:

"Cannot connect to the license server.

Error Details: The license server is not responding. Please check your network connection.

(support reference: NoNetworkConection -310)"

This is not true as i can ping the server no problem and i see that the traffic goes trough the network.

There is no antivirus active or firewall.
