Cannot connect over a local network, but works locally

[hatsmagee]

I get these warnings when trying to connect to the viewer(http://192.168.1.237:5000/viewer.html) from another computer on my local network and I do no see any video. Although, I can see video locally when I go to the broadcaster address and the viewer address. Any ideas?

app.listen(5000, '0.0.0.0', () => console.log('server started')); worked for me

const port = process.env.PORT;

app.listen(port, '0.0.0.0', () => console.log('server started'));

Serve pra quando estiver em servidor externo.
