BBB 2.3.0 Media could not reach the server (error 1020)

[acevedo...@gmail.com]

Hi,

I did a fresh install of BigBlueButton 2.3.0 on a fresh Ubuntu 18.04 bare metal server, but can't share my webcam or my screen. Every time I try to share my webcam I get the "Media could not reach the server (error 1020)" message.

I have also reinstaled my Coturn server upgrading to the Ubuntu 20.04 version, but still getting the 1020 error.

As suggested in other threads I have executed the following commands with this output:

# Potential problems described below

I don't know if the issue is because node and kurento are both listenning in port 8888 even when node listens for tcp and kurento for tcp6

What can I do to solve this issue?

PD: I'm using the same TURN server with my production BBB 2.2.36 without any trouble to share the webcam or screen
