Unity Package Manager Error - no connection with the Unity Package Manager local server process

OpheliaHed · Aug 5, 2020

I've checked multiple times and made sure all of unity is whitelisted on my computer.
I've reinstalled it multiple times. Starting to feel a bit defeated.

Here's the diagnostics report:

Hello,

Sorry to see you are having this problem. As per the diagnostic report, the Package Manager server is failing to start, but the reason is not clear. Could you please provide some more information such that we could have a better idea about the issue? Can you provide the logs (Editor.log and upm.log)?

To gather these files, please refer to the Log files section in Unity User Manual (https://docs.unity3d.com/Manual/LogFiles.html)

Please keep in mind these files are written over every time Unity is executed, so they contain only the information from the last launch of the application.

Thanks

I apologize for being unclear. It's because I myself aren't too sure what's wrong.
Both logs are from yesterday.

Here's the Editor.log:

supita_unity · Aug 6, 2020

thanks for providing the logs

is that the only information on upm.log? I can see there is an error, but it seems truncated the end of it. In particular what directory is the source of the illegal operation. Could you share the full content of the upm.log file?

Something that might be worth to try is move Unity installation under a different folder. I see it it is under a folder that starts with the symbol `#`, I never seen the character # being a problem, but maybe it is.

OpheliaHed · Aug 7, 2020

yeah I thought it looked weird too but that's all the info that upm.log has in it.
I don't know if this makes any difference but I had trouble with getting Unity Hub to work before. I installed it on my external SSD in a file called "#Unity" because I like to have it higher up in the list of folders. Unity Hub installed no problem but it wouldn't open properly. It was like the program opened at then looked like it closed. When I checked the Task Manager it was still running in the background though.

Seems like there's a pattern here with the # symbol. I have Unity Hub installed on another drive but the folder doesn't have the # symbol. But I have the Unity Editors installed on my SSD because I have more memory there. And there the folder as you see, have the # symbol. I'll try to redirect the Editors to another folder without the # symbol and see what happens.

OpheliaHed · Aug 7, 2020

Can confirm that it was probably the # symbol that messed things up for me. Redirected the Unity Editor to another folder without the # in the name and Unity opened up no problem.

supita_unity · Aug 7, 2020

Happy to see you found a solution, thanks again for getting back to me with all the information. I can confirm on my end that having # symbol in the installation folder is problematic, I'm submitting a bug to investigate the source of the problem and fix it.

Hey, I got the same problem. Please help me in fixing this one.

Hello,
I want to use Unity and I was very happy,UNTIL this error showed up
Could not establish a connection with the Unity Package Manager local server process. This is most likely due to a proxy or firewall configuration. Make sure the process [...] is reachable via HTTP on the IP address 127.0.0.1.

PLEASE HELP ME UNITY......

I have done many stuff like proxy and many things
My windows Version is windows 10 1903
I am new to UNITY so please help.
THANK YOU

Phoenix7 · Aug 12, 2020

Workaround for me:
- Turn all Internet connection OFF (WLAN,Ethernet)
- Start Unity Hub
- Open your project
- When its loaded: Turn your Internet connection ON

Works for me with: 2019.3.14f1 / 2020.1.1f1 (was not tested)
