    Of late i have been getting this error when i try to launch a unity project or create a new one. Could not establish a connection with the unity package manager local server process. This is most likely due to a proxy or firewall configuration.

    Hi @gsmax,

    It seems to be related to Windows Defender. Here, to quote my colleague from another thread.

    Are you on Windows 10? Did you just installed Unity and started having this issue? Did you have a previous version of Unity in your computer working, does it still work?

    Some users have reported than Windows Defender is causing this problem for them. There's a couple of approaches related to this:

    recreate the Defender Whitelisting rules for Unity: https://forum.unity.com/threads/cou...ger-local-server-process.746267/#post-5244935


    disabling Windows Defender: https://forum.unity.com/threads/cou...ger-local-server-process.746267/#post-5116958

    Hope you figure out soon where the problem lays on your end. Please when you do, come back and tell us what worked for you.

    Cheers,

    Supi​
