Unity 2018.3.x Cannot connect to Unity Package Manager local server issue

I upgraded from 2018.2.2 to 2018.3.1 last week, and then I can't open any projects or create new projects unless I use -noUpm.
I have set UNITY_NOPROXY with "127.0.0.1,localhost" and disabled all firewall and anti-virus.
If I install 2018.2.2 again (overwrite 2018.3) I can still open and create projects, so I'm wondering if there is something different on 2018.3.x ? (I've tried both 2018.3.0 and 2018.3.1 and they have the same issue)


Here is the Editor.log

And here is the upm.log

 

Hi @MorningStar,

As far as I know (and tried) there is no difference in the way we treat the way UPM connects to the local cache or the distant registry. We fixed timeouts in Closed Network situations so that the npm underlying registry reverts to offline faster, but this does not make you have retries like we see in your log, rather the reverse.

As for setting UNITY_NOPROXY with "127.0.0.1,localhost", you don't need to do it, Unity already does it.

Can you try something for me?

Go to your Unity installation, find Unity Package Manager. Make sure it is present in the installation. Through the command line start Unity Package Manager. On your browser type the following: http://127.0.0.1:10010/health

Please post the results below.

Hi,
I found the UnityPackageManager.exe in my Unity installation folder D:\Program Files\Unity\Editor\Data\Resources\PackageManager\Server
I started it through command line and typed http://127.0.0.1:10010/health in Chrome, the result is
{"status":"OK","nodeVersion":"v8.11.3","upmVersion":"v2.7.2"}

 

Hello, I'm having the same problem. I cannot start the editor in any version. I've tryed so many things but nothing is working. The IP adress in the host driver is ok, also the updates of my OS (WIn 10 in my case) are at the date. Sorry if I´m not seeing something obvious here, I'm not a programmer just a 3d artist trying to make things interactive. Please help!

This is the message I get any time trying to open the editor. Please, what could be making this happen?

 

@okcompute_unity Thanks for answering. I've tryed deactivating my firewall and still the same. I've not modified any proxy configuration since the last time I used Unity. When trying to open a project it stops at this point and then the same error window appears.

 

I have a similar error. Could someone help me out?

 

i also got the same error

 

It sucks, I've tried thousands of ways, I till can Nooooot connect package!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

Here is a way to make your unity project's red warnings go away ( I don't advice it cause I don't know if the packages were installed correctly ):
1. Reimport All;
2. Don't Update when it asks you "Would you like to update your project to always ba able to find the latest version of the Vuforia Engine in the fu*king package manager window?";
3. Clear
That's it, package manager really sucks!

 

I'm very confused as to what to do about this. Could someone please help??

 

I ran the diagnostics and this is what happened
