Stream does not start or shows no video (network)

On some company networks a stream page opens but the stream does not start, or the picture never appears. This page explains why and, at the bottom, what your network administrator can allow.

Why it happens

A stream needs two connections. First the stream page opens a WebSocket to our stream server to set the stream up. Then video, sound and your mouse and keyboard travel over WebRTC: directly over UDP when the network allows it, otherwise automatically through a relay (global.turn.twilio.com) on port 443. If the WebSocket is blocked, or both UDP and the relay are blocked, the stream cannot start.

What you can try first

• Open the same link from another connection (home internet or a phone hotspot). If it works there, the network is the cause.
• Turn off any VPN.

How to fix it (for your network administrator)

Allow, for your users:

• *.eagle3dstreaming.com on 443, including WebSocket (WSS).
• global.turn.twilio.com on 443 TCP (and 3478 UDP/TCP if possible).
