Same Package Manager problem for 2020.1.16 exit code: 216

Questions & Answers

I posted yesterday about this same issue with 2020.1.17. Today I thought I’d try the previous version just to see if it worked. I’m getting the exact same error. It cannot reach the package server for some reason. When I run the diagnostic all pass except one:

:x: UPM health check (FAIL)
Start the UPM process and call its health endpoint

Server exited unexpectedly. Exit code: 216

My antivirus has not given an alert about this or my fireweall.
2020.1.11 didn’t have the issue, I’ll try to go back to that. Just out of curiosity what is the ip address of the package server so I can check my logs?
Thanks!

I have exactly the same problem .
Version 2019.4.16f1 works fine.
The newer version 2020.1.17f1 and 2020.2.1f1
both ends with UPM health check error 216
Help!
Kind regards Hans

I solved my problem with UPM health check error 216.
First I checked that my Firewall allowed Unity Hub and the Unity program.
Then I set UNITY_NOPROXY to 127.0.0.1 and NODE_SKIP_PLATFORM_CHECK to 1.
After a restart of my pc, it worked. I was able to start version 2020.1 successfully.
