I'm creating a multiplayer game that uses a pc as a host, and any other device as a peer, meaning mobile phones and laptops.
It's usually working fine, but I had a friend come over try to access the game using their mobile on mobile data. It seemed to connect and join the room, but couldn't receive any messages from the host.
I then suggested she use her laptop, and again she failed. I asked her what wifi she was connected to, and it turned out that she was connected to my routers guest account.
It was I'd because it's worked fine for other people. I then connected her Wi-Fi to my main account and she was suddenly able to connect.
I then logged out of my game and turned off my phones Wi-Fi and tried to connect using my mobile data, and that didn't work either.
Anyone had that issue before? It only seems to happen with data and guest wifi. Yet works with normal wifi, both 2.5ghz and 5ghz.
