Question

Open Port 9001 for socket.io on Ubuntu Cyberpanel droplet.

I’m trying to run a Webrtc application and I need to open ports 9001, 3478 and 5349 on my ubuntu droplet. As you can see in the attached images, I’ve already set up Digitalocean firewall and added the ports to the ubuntu machine too. However, I still have a connection timeout error for socket.io on port 9001. Any idea on how to solve this issue? https://ibb.co/9TBWgsM https://ibb.co/BVFyM0f https://ibb.co/j5SKNX2 https://ibb.co/bsBXgRx https://ibb.co/bNHbHpC https://ibb.co/q0sp51c

Hi @sergiowilliones,

Depends on the feature you use, you need to open the following ports:

  • TCP Port 443 (HTTPS): outbound
  • UDP and TCP port 3478 bidirectional to the WebRTC server
  • UDP Ports 50,000 – 65,535 (RTP/sRTP/RTCP) bidirectional to the WebRTC peers. These ports are optional; if blocked, media will be proxied using TURN on port 3478

Do you use the transmission of secured streaming media (audio)? in this case, you’ll need to open udp/16384-32768.

Let me know how it goes,
