    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 :
    Code (csharp):
    1. Unity Package Manager Diagnostics (v0.1.8)
    2. ============
    3. Ran 7 checks
    4. ============
    5. 3 succeeded
    6. 4 failed
    7. ============

    9. Make an HTTP request to the UPM package registry
    10. >> Connection error.
    11.  
    12. ❌ Ping UPM registry (FAIL)

    24. ✅ Speedtest.net (PASS)
    25. Test the Internet connection using Speedtest.net
    26. >> Measured speed to the Speedtest.net server: 6.02 Megabits per second
    27.  
    28. ✅ HTTP proxy environment variables (PASS)
    29. Detect whether proxy-related environment variables are set (HTTP_PROXY, HTTPS_PROXY, ALL_PROXY, NO_PROXY, UNITY_PROXYSERVER, UNITY_NOPROXY)
    30. >> No proxy support has been configured through environment variables.
    31.  
    32. ✅ UPM health check (PASS)
    33. Start the UPM process and call its health endpoint
    34. >> Server start duration: 1312.00 ms
    35. >> Server response duration: 744.16 ms
    36. >> Server response:
    37. >> {"status":"OK","nodeVersion":"v12.2.0","upmVersion":"v3.14.1"}
    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.

    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
