Slow Editor Startup

Unity Engine

I’m having an issue where the Unity Editor splash screen takes a while to show up when starting the Unity Editor. It seems to take about 3 minutes dealing with licensing?

I’ve tried reinstalling Unity Hub and the Editor several times and with different versions.

Here is Unity.Licensing.Client.log. It shows about a 3 minute delay between two steps:

Hi there,

Sorry to hear you’re having issues…

The log seems to indicate that you’re behind a Firewall:

…
2021-08-04 00:58:09.702 - INFO - Unity.Licensing.Client.Communication.Controllers.UpdateLicenseController || Closed network detected. Falling back to Ensure license.

During that 3 minute lapse, the Licensing Client seems to be just waiting on the Editor to ask it about licensing.

My first educated guess is that the Editor is trying to download stuff from Unity and timing out. Could you check your Editor.log file for some clues about that? You should find it close to where you got the Client’s log, under the Editor folder.

If you’re required to go through a Proxy to access the Internet, you probably need to set some environment variables as mentioned here: Unity - Manual: Network issues

Another important question: what type of license do you have? I.e. Personal, Pro, Enterprise (floating)…? If it’s the latter and you’re setting the proxy env vars, you probably will need to add the Floating License Server’s IP to the NO_PROXY variable. You’d get that from your services-config.json.

Best regards,
Felipe
