Webrtc works on 3G but not on Wifi or Lan

Tue Oct 02, 2018 1:38 pm

I have configured Webrtc on a Raspberry Pi 3, created an noip (DDNS) account e made the port forwarding.

MJPEG works anywhere, like a cellphone with 3g, 4g or wifi. Or on a computer on a Lan.

But the Web RTC (Two-way Audio/Video) works only on the cellphone with 3g or 4g.

Image bellow:

I got the error message: ICE connection failed

Any Idea about this?

first make sure you understand how webrtc works with NAT traversal:
