Local LAN Multiplayer Problem PC (Host) to Nintendo Switch for Dissidia 012

[chidi]

I followed all of the steps and we manage to connect to the same room in Group Play. Everything goes smoothly: we pick the mode, characters, etc. When we both select begin, we receive the error message: "Communications were disconnected. Returning to Lobby." Not sure what I'm doing wrong here. The devices are connected to the same network. The IP address and port offset are the same. The PC has the "Enable built-in PRO as hoc server" ticked, and the Nintendo Switch does not have it ticked. I've tried with and without "Forced first connect". I've tried restarting both devices. Not really sure what else to do :(

Screenshots of settings and error message are attached.
