    If this is in the wrong group, please let me know where I should direct this question before you delete the question from this group.
    I put the question here since the description says that it's "For discussions, questions and feedback around the Unity Hub."

    I have a need to know what the ports in the title (38000, 38443, 39000) are used for. With the government cracking down on http traffic and the possibility of blocking the traffic that use these ports, I need to understand and hopefully provide an explanation of how they are used in order to try to let them stay in operation.

    To our scanners, these ports appear to have http traffic (or at least are responding to http protocols). I'm trying to understand what will happen to our environment of using Unity if these ports were to suddenly become blocked, or if there will be some future of Unity that will change the behavior of these port to not appear to be open http ports.

    Thanks,
    Chris

    One thing I know from experience is the whole unity proxy stuff doesnt work well or reliably, it half works but clearly not all code uses the same methods so some works some doesnt. especially at pain package manager and logging in.. If you need disk encryption beware that can hose all forms of compile time too.

    Does anyone have an update to this? We are experiencing something trying to access this port using SSL 2.0 / 3.0. No idea what might be doing so.

    Could it be a package trying to access a license through the port?

    well
    • Inbound TCP port 39000, accepting connections from localhost only: The Hub listens on this port to accept connections from Editor instances running on the local machine. This port must be open for connections from localhost.
    taken from the unity docs Unity - Manual: Unity Hub advanced deployment considerations (unity3d.com)

    I believe one of the others was an older version of unity.. eg its changed.... im sure i read it in a change log recently

    from a unity post on this forum 38000 is the colab toolbars fave place to be [Solved] Localhost Unavailable - Unity Forum

    Unity Relay seems to be 38443

    Thank you!

    We don't seem to be running Unity Relay - how did you ascertain that that was the port it was using? Is there any way to close it? Or to find out that we ARE in fact running it?

    Um....... I used a tool currently under NDA from unity so i cant honestly share but it claimed it was that and after all you'd think they would know their own stuff :p

    it could be something the ide uses as services and even if you dont use relay if you use one it opens more ...
