Could not establish a connection with the Unity Package Manager local server process.

Hi,I was trying to make my own game until two days ago.But i can't developing my game anymore because of unity's weird crash problem.And it says nothing,i did everything come to my mind.
i've shut off firewall,shut off windows defender,chanced my router,i did everything really.
But problem doesn't solve and i think problem is seems like major and complex,i don't think i can solve that problem because i am not an experienced computer engineer,i am just university student.
Please,im waiting your help,i don't wanna reinstall Windows 10 i cant reinstall because I have important information on my system.

connection status for http://127.0.0.1/ is ok.

i was installed Razer Cortex software and optimized my game and after that did system clean maybe that's why this problem come up i don't know.

Here is Editor log.

Please im wainting for your help,i don't have so much time i have to finish my game within 1 week.

 

Hi @samuelb_unity thanks for reply.
No,i have been using 2019.2.5f1 for long time.This problem is occurred suddenly.
Reinstalling unity didn't solve.
"could you try creating a new project in a different Unity version" i can't open any project,unity stops itself while loading package manager and after about 1 minute throws that message.
Now i've reinstalled unith hub,but this time it says "The application path cannot be opened".

 

@samuelb_unity
Yes i have 2017.1.0f3 version too.İ tried open my project with that version of unity without unity hub,and it has successifully started my project !
But in 2019 version problem is continues,i think there is a communicating problem between unity hub and unity.

 

same issue with unity 2019.2.5f1
proxy setting works with 2018, but its not installed via hub, the thing here is unity 2019 is inside unity hub folder and when you launch unity via proxy settings the editor doesn't load and throughs following error.

 

İ've tried all of unity 2019 versions but that problem always continue.
Problem is package manager of unity 2019 itself.
There is a big problem in here but sadly i have to finish my game in 1 week but how can i ? İ can't even open unity 2019 !

İ had use a lot of game engines and no one crash like this.
Reinstalling unity and change version doesn't fix the error.
Unity let me down.

 

Reinstalling windows has solved the problem.İ can't believe could be like that bug since 2017.

 

How do you fix this? Please help i want to get into developing and this seems to be one of the best but of doesn't work!

 

Hi Everyone,
I am getting the same error message when trying to create projects from Unity Hub.
I set the HTTP_PROXY and HTTPS_PROXY, but still no success.
Here are the results of our diagnosis test (the failed tests):

4 out of 6 checks passed:
{
"name": "Ping UPM registry",
"description": "Measure the latency of the UPM package registry API",
"result": "FAIL",
"detail": "No successful pings could be made in 5.393 seconds (0 failed)"
},
{
"name": "Ping UPM download",
"description": "Measure the latency of the UPM package download endpoint",
"result": "FAIL",
"detail": "No successful pings could be made in 5.098 seconds (0 failed)"
}

Any help would be extremely appreciated, we are currently unable to keep on going with the production!

 

Same problem occurs to me at my work environment, where we can only connect to the internet through our company proxy server. (At home, without proxy configuration, it works with all unity versions as intended)

HTTPS_PROXY and HTTP_PROXY environment variables are defined.

2019.2.0b9 was still working.

With 2019.2.8f1 and 2019.3.0b5 the following error occurs when opening a project:

"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 [******/UnityPackageManager.exe] is reachable via HTTP on the IP address 127.0.0.1."​

Running the package manager diagnostics gives me this log:

Hi @m_jaeger and everyone else struggling with this issue.
We figured out a way around this, which is working (at least for us).
Besides setting our HTTP_PROXY and HTTPS_PROXY in our environment variables we also set
UNITY_NOPROXY=localhost,127.0.0.1
When only setting it to localhost we still got the error, but adding localhost and 127.0.0.1 Unity starts up fine and the package manager is working as expected.
Hope this might help somebody else

 

Hi! Thanks for the suggestion @dschmuck, but I had already tried this and sadly also doesn't change the outcome for me.

I would be happy about any other suggestions from anyone

EDIT: just tried it with 2020.1.0a7, also didn't work

 

I am using unity Version 2019.2.6f1 and I downloaded the terrain tools package from unity package manager. I am a noob at developing games and wanted to start with terrain design in unity. However after I restarted unity I got this Wierd Error. - could-not-establish-a-connection-with-the-unity-package-manager. I did set my UNITY_NOPROXY variable but still get this error. I google only to rip my hair apart and finding nothing that worked. Hope this gets resolved soon!

 

I had the same issue as dschmuck and setting the UNITY_NOPROXY fixed the problem. How come that it is not working if I dont set the variable? Shouldn`t it work if its default?

 

thank you @dschmuck that fixed my problem

FYI, for unity diagnostics - I installed several versions of the editor. 2019.2.3f1 did not manifest the package manager problem. 2019.2.4f1 and newer versions of the editor did have the problem where it said it could not connect to the package manager on 127.0.0.1

I am quite certain that I did not have a UNITY_NOPROXY environment variable when I was having problems.

When I originally installed the editor, I did have the setting no_proxy=artifactory which I don't think should be relevant? I deleted it and that had no impact.

I tried a couple values for UNITY_NOPROXY. When is had UNITY_NOPROXY=127.0.0.1,localhost that didn't seem to solve my issue, but UNITY_NOPROXY=localhost,127.0.0.1 solved my problem, even though those two seem like they should be equivalent

Unfortunately, I can no longer test any theories using my current PC, because now that it's in a good state, I can't get it back into a bad state. Even when I delete my environment variable, or set it to a garbage value, like UNITY_NOPROXY=blarg, my editor still starts up fine now

 

The issue suddently resolved for me too. What fixed it for me was just doing a restart of windows after setting all the proxy environment variables(http proxy, https proxy, unity_noproxy). After that now everything seems to work with all unity versions.

 

Та же проблема!!! Не могу никак решить! Я новенький, хотел начать разработку игры, но не получилось...

 

Some problems from 2018 - all unity versions above 5.6.6. Can't connect package manager after windows 10 next update, then one week to test all finding in internet methods - and magical - again work. Until next win10 updating.
Current not working version - 2019.2.10, 2020.1

 

Бери анреал. Последний проект я даунгрейдил с юнити 2018 на версию 5.6.6 (это последняя версия без package manager, и самая стабильная - но на ней в гугл не берут), финалку обратно на 2018 для релизного билда.

 

Breaking news - when you add program to white list, or turn off windows defender - there's nothing changed - defender still to work, and block unity.
Microsoft doesn't give you real control on defender - only imitation.
If you want to work with unity - you must to make selection - defender or unity, and if selected unity - to kill defender.
How to kill defender:
- press Win + R keys, tape regedit - and press Enter.
- in editor window move to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\mpssvc
- on right panel twice click on Start parameter
- enter value 4
- restart windows and run unity.

 

how do i do this

 

6 out of 6 passed but it still doesn't work
hers my log:

}
]

 

In my case, I could solve this issue by deleting Unity folder under the Roaming data(%AppData%/Roaming/Unity).

 

I had just updated to 2018.4.12f1 and had to have the proxy values to be able to sign in, in the hub but hit with the package manager error and it wouldnt load into the editor unless I removed the proxy settings. But this meant I couldnt sign in or then use the asset store. However the UNITY_NOPROXY=localhost,127.0.0.1 value seems to have got it working, so my guess is that the editor is not defaulting to this for some reason

 

[Package Manager]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[C:/Program Files/Unity/Hub/Editor/2019.2. 0b1/Editor/Data/Resources/PackageManager/Server/UnityPakageManager.exe] is reachable via HTTP on IP address 127.0.0.1.
Sir please solve my problem
& I'm waiting for your reply......

 

Hey, i have tried your way, and it works well

So i go to, C:\Users\(account name)\AppData(sometimes it's Hidden)\Roaming\Unity then delete all files in there because i can't delete the folder

And to another tips unhide theAppData folder, select View menu in Explorer, tick the Hidden items in Show/hide ribbon

 

It doesn't work for me. Tried with versions 2019.2.14f1 and 2019.3.0a12

 

Hi Community,

One combination of solutions that worked for me was as follows:

1. Firewall White-listing of the editor program:

Go to windows firewall -> Advanced Settings -> Inbound rules - > Create new Rule-> type: program -> Complete path to the unity editor -> Allow Connections -> Give it a name -> Save.
​

2. Setting Environmental variables:

HTTP_PROXY, HTTPS_PROXY and UNITY_NOPROXY=localhost,127.0.0.1

​

What baffled me is that the Rules are already existing (probably installation set-up takes care of this), but it doesn't work. The same rule that I explicitly create (or in this re-create) seems to work.
It's high time that Unity adds an option in Hub to set proxy. I had heard this feature being on the road map from a Unity employee, but haven't seen any progress in this regard. PLEASE DO IT!

best,
Ani​

 

well for me its solved


i applied below



beside latest answer from @anirudhnandavar

 

Help me!

 

Local server error can be resolve. You should open Intermediate Server from your Connection Settings.
You may have a Virus. This buggy can change these settings. "Use Intermediate Server" not select. If selected in your computer, you should uncheck that. Check the Auto Only. Have a nice day!

 

Solved in my situation.
It seems to me that the proxy blocked for local addresses.

- Open "LAN Settings" on Windows
- Checked "BYPASS proxy server for local addresses"
- other settings might be set correctly on your situation

hope

 

I Solved My Problem By uninstalling Avast Antivirus And Turning Off Firewall

 

Had the problem when I migrated my project from 2018.3.14f1 to 2018.4.17f1. The newest version kept having the "Could not establish a connection with the Unity Package Manager" error while if I loaded the project with the previous version, it was working flawlessly.

I added the UNITY_NOPROXY=localhost,127.0.0.1 environment variable and it's working now.

@unitydevs: if it's not the appropriate fix, what would be a good one? Thanks

 

Every time a new file is created or opened in the Unity Hub, an error appears like the first picture. When you restart and open the computer, it does open. However, if you close the file and try to reopen it, an error occurs again. It was useless to try reinstalling the program by asking questions in various places and to erase all the vaccine programs needed by public organizations. Every time I opened the file, an error occurred and I was at a point where I could not learn. to be in need of assistance

 

Thank you.

Right this?

 

May I ask you a few questions?
1. Is this a common error?
2. Is it a unique problem with my computer?
3. Do you have any idea why an error is occurring?
4. Will there be the same error if I buy a new computer?

Thank you for listening to my problems and trying to help. I'm sorry to bother you.

 

Can you solve the problem? if the answer is positive, how was it?

 

I don't think it's working... I plan to buy a new computer in a month, and if there is a problem with that computer, I will try again... I'm sorry... I really appreciate your help.
