JItsi showing black screen when more than 2 participants join

jamie_amde · April 6, 2020, 7:40am

Hello guys,
i have been trying to configure Jitsi on local server and faced the problem stated on the title.

open ports on Firewall
443, 80, range 10000-20000/UDP

i understood that it is a videobridge error because it is not p2p anymore for more than 2 people joining (if i’m not mistaken).

can anyone help me on this?
thanks

You only need 10000 UDP, not that full range.

Have you followed the advanced instructions here?

# Jitsi Meet quick install

This guide helps you  ___host your own Jitsi server___. If you want to have a video conference without setting up any infrastructure, use https://meet.jit.si instead.

This document describes the required steps for a quick Jitsi Meet installation on a Debian based GNU/Linux system. Debian 9 (Stretch) or later, and Ubuntu 18.04 (Bionic Beaver) or later are supported out-of-the-box.

On Ubuntu systems, Jitsi requires dependencies from Ubuntu's `universe` package repository.  To ensure this is enabled, run `apt-add-repository universe` at the command-line.

_Note_: Many of the installation steps require elevated privileges. If you are logged in using a regular user account, you may need to temporarily increase your permissions (for example, by using `sudo` for individual commands).

## Basic Jitsi Meet install

### Set up the Fully Qualified Domain Name (FQDN) (optional)

If the machine used to host the Jitsi Meet instance has a FQDN (for example `meet.example.org`) already set up in DNS, `/etc/hostname` must contain this FQDN; if this is not the case yet, [change the hostname](https://wiki.debian.org/HowTo/ChangeHostname).

Then add the same FQDN in the `/etc/hosts` file, associating it with the loopback address:

    127.0.0.1 localhost meet.example.org
