Due to the requirement of changing the SocketSubsystem to work with PlayFab Party and Lobbies, this breaks any functionality in the project which may have existed with the use of beacons. Beacons are used as a way to interact with a server before committing to a map change
This can be reproduced by using any beacon set up with the DefaultEngine.ini change to for the PlayFabNetDriver. Unreal provides a example beacon class which can be used. You will get the following log:
LogOnline: Warning: PLAYFAB: FPlayFabSocketSubsystem::GetAddressInfo is not supported on PlayFab Sockets
LogNet: Error: No binding addresses could be found or grabbed for this platform! Sockets could not be created!
LogNet: Warning: Failed to init net driver ConnectURL: *TargetAddress*: No binding addresses could be found or grabbed for this platform! Sockets could not be created!
I'm working in Unreal 4.27.1 but I assume this is an issue in all versions.
