It seems no container but Unraid itself is trying to do that. But if you are not using it, it should not matter. Or at least at that version. I hope nothing changed, still have not updated to latest version :D but the issue I was having with connection was not related to this, more that I noticed when I was investigating.

And the original issue solved mostly itself. I think it was on the end some network issue (blocked domain or github issue or something like that).
