The fixes we implemented to get Unity 4.6 to access the asset store do not work for 5.1.
With 4.6, our firewall people allowed Unity to access kharma.unity3d.com and I ran Unity from a BAT file with some proxy info in it that allowed Unity to connect to the web.
Unity 5.1 doesn’t like the same tricks. It appears the first thing it does is check if you are logged onto a Unity account. Unity says it can’t log me on and my only option is to work in offline mode. Is this a different server that needs to be allowed by the firewall? If so, what do I need to ask the firewall team to add? Is there a url like kharma.unity3d.com?
As far as i can tell (using wireshark) Unity connects to “core.cloud.unity3d.com” via https (port 443). At least that’s what is used on the login screen.
When Unity is started it also connects to “kharma.unity3d.com” which seems to be a synonym for “sl-http.unity3d.com”. That’s at least what the dns server said ^^.
The communication to that server is also a SSL connection (Port 443).
Can’t see anything special besides that. Well there are some google analytics requests, but i also run firefox in the background, so who knows where that’s comming from ^^.
