Hi, I’m having trouble with getting Mac w/OSS working, it seems to work mostly fine when I host with Windows, but strangely, when I host with Mac, I cannot seem to join. It seems to try for a while and then time out after a couple minutes:

Very strange: I am also getting this error on the Mac when I start the server:

etc
I’m using 5.8, xcode 26.3, any help would be appreciated, thank you!
