When starting Unity 2017.2f3 I directly get the “Sign into your Unity account” pop up.
Clicking “Sign in” I get “Service not available please try again later.”
We don’t have any internet access, and use remote workstations so unplugging the network is not an option.
I’m not getting the “No network connection” screen.
Instead the login screen, where “Sign in” is only option - clicking sign in throws “service not available”
Nope, it is still there. In my case it is so that I have a server with network connections but not internet access, and I am not administrator. So when I start Unity it goes directly to the sig-in page, and I have no options to do a manual activation.
