Unity 2019.3.0a12 does not start

Hi guys,

It seems like a lot of people are getting the following error when trying to launch the a12 editor.



It does not matter if you've installed it through the hub or not. The only person I've spoken who has gotten the a12 editor to work, seems to be using a paid/professional license.

Edit
Tesrym on the Unity discord has managed to find a workaround. I can confirm it works.

 

I'm not having this problem with my personal licence.

Maybe you just need to log out in the hub and log in again?

 

No, I've tried everything, rebooting, killing the process, installing it without the hub, with the hub, with and without a working internet connection, even reinstalled after it officially appeared on there, and a lot of other people seem to be having the same problem. But the workaround seems to have fixed it.

 

The workaround is logical; I should have thought about it. Sorry.

 

I'm getting the same error.

Here is the content of the entire editor.log, in case it helps to provide some insight:

Getting the same error.
I noted that my Hub shows a wrong date for the "Last Update" license field - it's in the future. Not sure if it has always been like this though.

Above workaround (deleting the ulf) works and still shows the same dates.

 

Same Issue here.

Also, OPs workaround has completely hosed my account, the licensing page just has a progress bar and all buttons disabled forever. The log shows it finds no files, disconnects and does nothing. Restoring the deleted files does nothing. Signing out and back in doesn't help either.

 

Thanks I got the same issue

 

Same here

 

Oh my, guys, do you even test that what you release can at least start under all valid licensing conditions? I understand that this is "alpha", and, like nobody guarantees anything, but this is a bit too much. Thanks for fixing, of course, but how can I sleep now.

 

Just use the workaround mentioned in post #1. Do that each time you have a similar problem.

 

I have a similar issue with this version (Unity does not start) on Mac OSX [10.14.5 (18F132)].

It doesn't complain about licenses, but I tried the workaround above just in case. No dice - same issue still. It just closes down immediately upon starting up. No crash as far as I could see, but here is the log:

Code (CSharp):

Any ideas?

 

I also had crashs.

I also had some crashs at launch unrelated to licences and I managed to fix it by renaming the last scene I opened the previous time I worked with Unity (aka the scene Unity is trying to open when launching).

 

Can you suggest any other workarounds that might work until the next release rolls out? None of the workarounds on this thread work for me.

 

Hey, If I read correctly my bug report files, I think have the same issue with 2019.3.0b1
No workaround is working :/ The editor opens but will crash every 20 seconds.

I'm getting the same error in Cloud Build using Unity 2019.3.0b8 (also happens with b7)

Code (CSharp):

1. 4: [Unity] [LicensingClient] ERROR Failed to connect to local IPC
2. 5: [Unity] DisplayProgressbar: Unity license
3. 6: [Unity] Initialize engine version: 2019.3.0b8 (7eb5456f98b4)

Any sense when this will be looked at?

 

Edit: Reported at Case 1197747

My editor is doing the same on 2019.3.0b10 occasionally crashing with no error popup. Check the editor log at 14:29 right after the editor suddenly closed to see

1. [LicensingClient] ERROR Failed to connect to local IPC
2. [Licensing::Module] Failed to connect to channel: LicenseClient-Rob Farthing
3. [Licensing::Module] Successfully launched the LicensingClient

9. LICENSE SYSTEM [2019118 14:29:51] Next license update check is after 2019-11-09T07:49:56

 

Are there any ports which need opening for Unity's licensing checks ?

 

I'm getting this issue with Unity Hub 2.3.2 and i'm using the latest 2019.3.15f1 and no workaround is working. i've tried everything.

 

this is happening because i m using WiFi or i'm offline. once i change over to Ethernet the server checking that happens goes through and then the editor opens up. why cant i use unity offline??

 

It's very strange. If I disable Wireless connection I have same issue.

If I enable Wireless connection the issue is gone.

But I am not using Wireless network on my computer.

 

It's useful.....solve my issue

 

I can confirm that this is working!
Wasted and entire day on this

 

I have same problem and try a lot can not solve it.Now, consulte this answer，I enabled my ethernet (I use wifi before) and solve the problem.

 

Unity: 2019.3.15f1
MacOS
Unity Hub: 2.4.2

I've got same trouble while using in-TeamCity created build pipeline for Unity iOS / Android builds.

At some step, when opening project with command line, next lines appeared and build went hanging.

[16:17:33][LicensingClient] ERROR Failed to connect to local IPC

[16:17:33][Licensing::Module] Failed to connect to channel: LicenseClient-builder

[16:17:33]Launching external process: /Applications/Unity/Hub/Editor/2019.3.15f1/Unity.app/Contents/Frameworks/UnityLicensingClient.app/Contents/Resources/Unity.Licensing.Client

[16:17:34][Licensing::Module] Successfully launched and connected to LicensingClient

[16:17:34]Entitlement-based licensing initiated

[16:17:34][LicensingClient] Licenses Updated successfully in LicensingClient

As described below by @LSPredator, seems like it's an internet connection trouble.

Solution that helped me is to disable ethernet connection and connect to local wifi point.
Right from this point, build succeed.

 

I'm using a Mac. I downloaded Unity free version, but the license for unity is not found and 'unity hub' is not available in my region. Please help
