I have been trying to use the roll 20 app, but it will not connect to the server unless my tablet is connected to the mobile hotspot from my phone. once it is connected I can swap over to the house wifi and the app will work correctly for about 2 hours or so but it eventually kicks off and I have to reconnect to the phone's hotsopt to get back into the server. I have tried launching the tablet app before opening roll20 in firefox on my computer, and the other way around, the only way I can get the app to connect is going through my phone's hotspot. I have tried connecting from other wifi routers, friend's houses, and still unable to connect. Does anyone know what would cause this and how to correct it?
