Install issue - reconnecting when 2 users or more

Hi all,

I followed up this tuto to install a jitsi instance on my own server (ubuntu 18.04)

  • Connecting one user is ok but has no interest ;-))
  • Connecting a second user do not display video on FF and always reconnect
  • On chrome, I’m able to see both videos but it is also reconnecting after 30 seconds …

The error (js console) is that one :

I’m stucked … Thanks for your help !

Port forwarding or firewall.

Check https://jitsi.org/qi advanced section

@damencho : thanks for your quick reply. You got it ! it seems FirewallD was my default firewall and I opened ports on UFW.

Have to configure all this on startup. Thanks again.

(By the way, I know UFW is now default firewall on ubuntu, but it could be nice to have a firewallD / iptables alternatives in your install tuto)
