Official **READ ME FIRST** Troubleshooting connection/loading project issues with Package Manager

For those who went through the readme, error still happening, all you need to do is nuke the end of your json, like so.

Code (CSharp):

I'm unable to use the Package Manager since saturday. I did everything I found in the internet trying to fix it.
I deleted and recreated the firewall rules, deativated the antivirus, logged out and logged in (from Unity Editor and from Unity Hub), restart the computer and Unity but I still get the error.

[Package Manager Window] Error while getting product update details: System.InvalidOperationException: Failed to call Unity ID to get auth code.
UnityEditor.AsyncHTTPClientone (UnityEditor.AsyncHTTPClient/State,int)

I don't know what to do anymore. Everything works fine in 2020.1, but not in 2020.3

 

I am trying to fix this for weeks.. Actually tried everything, 2020.1 work great, .2 and .3 will show this error. I don't know what to do now

 

I'd suggest file a bug report so we can take a look at the log files to see what is going on if you've tried everything in the pinned thread.

Hey Unity, when are you going to support continue for downloads in the package manager? When I'm downloading anything bigger than 10MB I have to go outside to fart in case it causes the package manager to fail.

 

Code (CSharp):

1. Cannot perform upm operation: self signed certificate in certificate chain [NotFound]
2. UnityEditor.EditorApplication:Internal_CallUpdateFunctions ()

I built an unity packages server and configure the SSL with a self signed certificate, unity needs an option to ignore that. Like npm strict-ssl false or cafile=C:\Users\someone\ssl\local-ca.crt. If there is no already an option. Is seems like Unity does not access the certificates of the OS (Windows 10). Or the package manager it self. maybe it's a separated system?

 

Trying to download or upgrade Burst package had been really painful for us, it's a 300+MB package and Package manager just stall forever.

It's worse if you are launching a project without the correct Burst version in cache.

 

This is very interesting. I've never experienced this before. I was looking forward to the shadow improvements for URP going from version 2021.1 to 2021.3 and surprisingly I can't even get into the engine because of that package manager issue.

The only clue I have is when I install it the firewall first install notice has the public network greyed out. I followed some instructions but no matter what is done on the firewall the error will not go away. This is a critical bug it has nothing to do with user side or firewalls because as you can see most people in this thread cannot solve it.

I think this Unity version I'm on may be the last one because it's become dangerous to upgrade now.
Also on a unrelated but related note I've also got 6 bloody Unityhub.exe instances now @ 300mb of Ram????
I used to love this engine back in the early days it was so light, things were so simple it used to do everything including packages with just 1 instance....I've spent thousands of dollars on mostly asset store things and plugins while Unity has added so little in things most people will use and what feels like 10 x more bloat and resource usage . 1 step forward 2 steps back....I need help lads.

 

Hi @unityteam/ @UnityMaru / @supitaUnity ,
I am neither able to launch or upgrade to 2021.3.0 or 2021.3.1 Unity nor to the 2020.3.33. I get the upm launch error.
I had no such issues till unity 2020.3.31. I am using unity 2020.3.31

I have tried disabling firewall and / or set up the inbound rules and reinstalled but the issue persists.

The diagnostic report is as follows

I have Windows 7 and I cannot run latest version of Unity (2021.2.*, 2021.3.*) because of this bug.

Symptoms:

Error message:
Failed to start the Unity Pacakge Manager local server process. Make sure the process is not blocked by Windows Defender or other anti-virus configuration.

I went to the specified path and launched UnityPackageManager.exe manually. It fails to start with the error,
Entry point to procedure EventSetInformation is not found in DLL ADVAPI32.dll.
(Точка входа в процедуру EventSetInformation не найдена в библиотеке DLL ADVAPI32.dll)

Resolution:
I rolled back to v2021.1.22f, which seems to be compatible with Windows 7.
You can download it from Unity download archive:
https://unity3d.com/get-unity/download/archive

 

Hello guys,

Request your ETA on the Windows 7 fix.
It's been almost 6 months now.
Many of us are not able to upgrade from unity 2020.3.xx to 2020.3.34 or 2022.1.0f

 

Also Windows 7.

I try launching Unity 2021.3* and it always crashes at startup. Diagnostic system says its the package manager health check.

I try to launch package manager and get this error:

"The procedure entry point Event SetInformation could not be located in the dynamic link library Advapi32.dll."

Other versions of Unity prior to 2021.2 work fine. 2019, 2020, all good to go. Not 2021.3.

 

Workaround that I used. [Warning** do it at your own risk]
Deleted the package manager folder from 2021.x (2+ gb)
Default path [C:\Program Files\Unity\Hub\Editor\2021.3.2f1\Editor\Data\Resources\PackageManager]

and copied the package manage from 2020.x

Default path -- [C:\Program Files\Unity\Hub\Editor\2020.3.31f1\Editor\Data\Resources\PackageManager]



But I am going to wait for an official fix. I wont risk my main project to this workaround

 

I updated windows 7 to KB4474419, and now I am able to use 2021.3.3.

 

Here are two things that fixed this issue for me:

1. Open your project using Unity Hub (opening the Editor directly causes package manager to not connect at all, at least for me).
2. Make sure Windows is reporting an internet connection. Windows 10 has a bug where it says you have no internet connection when you do. There are various ways to fix this (often resetting the network adapter or router is enough), but it seems that Unity relies on Windows reporting an internet connection before it will even try to connect with Package Manager.

 

This worked perfectly for me, thanks m8

 

Hello, my IT guy and I have been constantly running into issues installing some packages through the package manager; we keep getting the socket is closed error. Some packages, which I assume are automatically installed with Unity, don’t have issues with installing/upgrading through the package manager. We’re currently trying to use Unity 2022.2.1.6f1 which is where most of this issues arise, but it also pops up in earlier versions as well.
We’ve followed all the instructions in the first post of this thread as well as the following sites, but keep running into issues with the socket being closed.
https://forum.unity.com/threads/network-configuration.590470/
https://docs.unity3d.com/2022.2/Documentation/Manual/upm-config-network.html

The socket closed error comes up for the below packages while others (e.g., HDRP, FBX exporter, AR Foundation, etc.) were able to install without any issues.
XR Plugin Management 4.2.0
Visual Studio Editor 2.0.15
Netcode for GameObjects 1.0.0

So it seems like the required “whitelist” domains provided in the network configuration documentation does not include all domains that need to be whitelisted. Furthermore, when trying to install the XR Plugin Management 4.2.0 my IT guy saw that Unity was trying to access different domains but was blocked (socket closed error) each time I tried to install it through the package manager. Below are some of the blocked domains:
a23-54-68-57.deploy.static.akamaitechnologies.com
a23-56-12-61.deploy.static.akamaitechnologies.com
a96-7-212-56.deploy.static.akamaitechnologies.com
a23-208-8-58.deploy.static.akamaitechnologies.com

Attached are the reports produced by the package manager diagnostic tool. Any help someone can provide as well as an updated list of all domains that need to be whitelisted would be appreciated.

 

install KB3080149 solved problem, win7 x64

 

THANK!!! This is the only working solution that really helped!

 

Unity 2022.1.23f1 here. I started using 2022 so that I could change the download directory to a separate disk, but I also had trouble in 2020 and 2021 as well.

I have a LOT of assets that I purchased on the store, so when I open the Package Manager and switch it to "Packages: My Assets", it takes a little while to pull the list. This is understandable. But then each time I click into the search box to find a specific asset, I get this progress bar and a message that it's "Waiting for Unity's code to finish executing".

Sometimes I wait for the progress bar to finish only to have it pop up again when I click to search. This is extremely frustrating as something that should take 30 seconds could take many minutes. Then for each asset that time compounds.

I bought my assets on the store because it was convenient, but this being the only way I download them is not convenient.

 

After a week of trying to solve this problem, i found a solution.
I'm on Windows 7 SP1 with Unity 2021.3.18f1, so it may not work for other OS/Unity version.

I just had to install the KB3080149 update.

I also did allow everything in my Defender/firewall, but previously to the update installation so it might have worked even without changing thoose settings.

 

I recently got issues with connections in package manager, too. I am using Kaspersky Internet Security, version 21.3.10.391(j), and for me worked following solution:

1) Go into antivirus settings, General, and disable "self-protection" (down below; English name can be a bit different).

2) Exit the program.

3) Delete all content of the folder "C:\ProgramData\Kaspersky Lab\AVP21.3\Report".

4) Restart the antivirus.

5) Enable self-protection.

 

Please,
I need to receive help in diagnosing this issue
My Unity projects don't open

(Windows 11, and Unity 2019.3.9f1)
(notebook Lenovo Legion 5)

Test the Internet connection using Speedtest.net, result: "FAIL", detail: Connection error
No proxy support has been configured through environment variables

The diagnostic report and the accompanying log are attached

Thanks!

 

Solution: Don't use win 11. Windows is bananaware for at least 3 years after first release. Sorry, couldn't resist.

 

I noticed that 1 of 3 of my Unity editors didn't have the discussed error and it made me think.
That specific editor is installed on secondary HD instead of primary.
So I :

• uninstalled the problematic editors and Hub
• deleted leftover Unity folders in "Users/User/Appdata/Local" and "Users/User/Appdata/Roaming"
• reinstalled the problematic editors in the secondary HD and Hub in primary HD

Fixed for me.
