[Package Manager] connect ETIMEDOUT 35.238.21.138:443

Hello,

I got this error for the package manager...

Code (csharp):

1. [Package Manager] connect ETIMEDOUT 35.238.21.138:443

I'm behind a proxy, everything works fine, asset store works, downloading assets aso. works fine...

What can I do?

 

is there a solution for a "Proxy server using a self-signed certificate"

 

Same problem here. Please help to resolve!

 

I have encountered the same problem, how to solve it

 

Without changing anything (router, software, permissions, etc.), for me it works only sometimes and sometimes not.
As an example: I've tried to install the FBX-exporter and had to click several times on install, getting the annoying timeout-message.
On the other side, something has changed, because in earlier times I also didn't get the full list of available packages and now at least I get the list, but can't install some packages.

 

Same problem here, ran the diag tool and got the following result :

I'm pretty sure the problem is server-side.
If you try to open https://35.238.21.138/ on your browser while having upm problems, you get a 503 error with message "No server is available to handle this request."
Even though pinging the IP succeeds, so some web-server should be crashing or something like that.

 

Hi Dante,

Did you solve this issue? I had the same issue today and the same package manager diagnostic result. Tried to reinstall unity, added exception to firewall but nothing help.

Unity, your server is down again!

 

Алогично. Кто то решил проблему? или надо просто чуть чуть подождать?

i solved it by setting unity proxy manually, go to your proxy settings and get the IP and Port in my case it was 127.0.0.1:7778

create a UnityLaunch.cmd file and place in desktop, containing this:

Code (CSharp):

1. @echo off
2. set HTTP_PROXY=http://127.0.0.1:7778
3. set HTTPS_PROXY=http://127.0.0.1:7778
4. start "" "C:\Program Files\Unity Hub\Unity Hub.exe"

close all unity editor and hub, open this file instead.

 

A new error appeared after opening this cmd-file... Do you know what I should do about it?

[Package Manager Window] Cannot perform upm operation: Unable to perform online search:
Cannot connect to 'packages.unity.com' (error code: ENOTFOUND). Verify your environment firewall policies allow connection to this host name. If your system is behind a proxy, verify your proxy environment variables (HTTP_PROXY and HTTPS_PROXY) are properly set. [NotFound].

Get your port from Settings > Network & Internet > proxy > scroll down below "use a proxy server" see your port there and edit it
