Licensing requires Internet access - however, after some time of inactivity the port used to refresh the license file is closed. Opening Internet Explorer and loading the URI to the home page of the license provider also open the cloud connection.
Solution:
Automate opening the web page (URI) at regular intervals by means of a powerShell scipt
Content of script:
Invoke-WebRequest -Uri 'http://test.com' -Proxy 'http://10.22.19.23:8080' -ProxyUseDefaultCredentials -UseBasicParsing
Run command:
powershell.exe -file C:\scripts\proxy_refresh.ps1
Automation was accomplished using the free version of 'System Scheduler' from Splinterware.
