Hi, I might have done this myself, but I can't seem to fix this. Join doesn't work on my home network. It works just fine at work, or even if I connect both my phone and laptop to my phones hotspot. I've been forwarding some ports here and there for other stuff (I'm using external 443, 155, 160, 175, 230, 6680, 8883), and can see that "Back to my Mac" automatically forwards port 4500 and 5353 to my laptop. Other than that, I can't really think of what the issue should be. It's been "not working" for a while (or sometimes slightly working, I can sometimes get my new messages to appear in the chrome add-on, but I can't text from the add-on, and after a while, it tries to refresh, and hangs forever). And I seem to remember it has been working at some point while most of the forwards have been set up. I've tried the "diagnostics", and it gets stuck at "Sending Push to server..." Any ideas would be appreciated. Cheers!
