Is rcon set up correctly? It needs to be Set up in both factorio and the mod settings in factorio. If it is set up properly, Try running the bridge after the world is loaded.

Wait, is it not enabled by default? I checked multiplayer server settings and there seems no rcon option. And I have checked local-rcon-socket parameter, it's set to 127.0.0.1:27015 (default)
