Not working for more than 2 people in the room

Yes, and right now I am forwarding everything just to be sure.

But I now think it is definetly a firewall problem.

By opening chrome://webrtc-internals before the conference you can check the last setRemoteDescription in a peer connection tab and check whether you see the bridge public address, if so jvb is configured correctly and it is firewall/port forwarding issue.

Hi @damencho,

I do not see the the bridge public IP:

Make sure you are checking setRemoteDescripotion and on that page there are several tabs, if you have one meeting open in chrome you will have two tabs there one for the p2p PeerConnection and one for the jvb PeerConnection, chack jvb’s one(I know it is jvb by seeing the addresses). Even if there is a problem you will see at least the internal address from the network interface that jvb can discover by itself. If you have two tabs open in chrome you will have 4 entries and so on.

Yes, I don’t see the IP address.

I see only IP4

You are looking at the wrong place. Here is how it looks on

Sorry for that,

it is advertizing the internal IP address:

a=candidate:1 1 ssltcp 2130706431 443 typ host generation 0
a=candidate:2 1 udp 2130706431 10000 typ host generation 0

is this normal?:

netstat -tulpen

udp6 0 0 :::* 999 11848 498/java

Did you restart jvb after setting NAT_HARVESTER_LOCAL_ADDRESS and NAT_HARVESTER_PUBLIC_ADDRESS? Where did you set it, in which file?

I set in in /etc/jitsi/videobridge/

And yes, I have restarted the whole server

So check the file again for some extra spaces or something unusual, apparently those settings are not taken into account.*^/([a-zA-Z0-9]+)$

Seems fine.

edited the file again, check for spaces.

All is good but it still advertises the internal IP

You did service jitsi-videobridge restart? If so show us the jvb logs, this is strange.

This is weird indeed.

After I made the changes I restarted teh server and it didnt work.

Now I ran service jitsi-videobridge restart and it works and shows the correct IP

@damencho thanks a lot. It is working :slight_smile:

Actually I turned the server off, tuned it back on and had the same problem.

had to do : service jitsi-videobridge restart for it to work again.

Seems you are not rebooting your server but suspending it :slight_smile:
