Problems connecting clients

Hello, I’m trying to connect clients to the network license server but I get the message: “Could not checkout license: cannot connect to license server on host”.
I use the following steps to connect but did not work: http://download.toonboom.com/files/kb/connect_client_2/
Anything I should do more in addition to configure Server License Wizard?
Thank you very much.

Hi. you better contact Toon Boom support if you have not.
