Ping Lobbies and Servers
As of SteamCore:: 1.18 you can now ping lobbies using Blueprints and the SteamSockets Plugin (built into unreal engine)!
Begin by Configuring SteamSockets
SETTING UP LOBBY PING DATA
Create a Lobby and set the HOST_PING data
GETTING PING VALUE
This will print the ping value from the lobby owner
Get the ping value and assign it to UMG / lobby list
THE RESULT
The unknown lobbies are because of using Steam AppID 480, it will list irrelevant lobbies.
