Sometimes when you have multiple devices--such as consoles, computers, tablets, and phones--all simultaneously on the same network, especially when trying to connect to a single game server, there's a chance that one or more players will be disconnected from the server.
This is likely due to your NAT settings preventing the server's signal from reaching all the devices on the network.
This can usually be solved by activating UPnP on your router, as well as making sure that all devices on the network both have UPnP support, and that it is set to active.
To ensure that your connections will be stable:
Once you've ensure UPnP is activated on your devices, multiple consoles and/or PCs on the same local network should now be able to all simultaneously connect.
