We are having an issue running this to test it. We are running on a test server in our production environment, a Windows 2018 server that has Lync Core Components installed and has access to our Lync environment. When we attempt to install on this server, we get the following error:
“An Internet connection is required to validate your license. Please make sure that you can access https://theucguys.com, and try again.”
None of our servers in the production environment are allowed by security policy to have Internet access via port 80 or 445. Is there a way to overcome this issue?
