    Hello, I am building a game where you can join a match and while in that match connect to a friends lobby. However I am running into some issues when I try to disconnect from one server to connect to another. What steps do I have to go through to "tear down" an active connection so that I can safely run
    Code (CSharp):
    1. World.GetExistingSystem<NetworkStreamReceiveSystem>().Connect(networkEndPoint);
    without getting any undesired behavior.

    you should add a NetworkStreamRequestDisconnect component to the connection. This will disconnect the client from the server at the beginning of the next frame.
    You then should just wait until the connection has been destroyed before calling the Connect again

    Can I safely GetSingletonEntity<NetworkStreamInGame>() to get the connection entity on the client? If not, is there any singleton I can target to get the connection entity?

    The presence of NetworkStreamInGame is handled by your own connection flow/logic.
    So if you guarantee that it's been added to your network connection and won't be removed, sure.
    Otherwise, you can just use NetworkIdComponent to identify connection entities or the connection singleton on the client.
