Internal Error:Environment fault

Internal Error:Environment fault

  
Hi, i'm trying to publish one a eSpace work, but i'm getting this error
" Internal Error
Environment Fault: Unable to contact OutSystems Deployment Controller Service. Please make sure this service is running on 'localhost' to obtain licensing information ".
I click on Administration Tools in Start Services, I go to configuration tools and the testing connection is always ok, however when I'm going to publish, the error mantains.
This error only occurs when i'm connected in a different network connection, at home and in the client. In my office is always fine. I need to configure something, when I change the network?
Thanks in advance
