Connection error Audio (ICE error 1004) with Docker BBB

[olivier-vailleau]

Hello, I'm trying to use bbb with Docker. I did 3 differents installations that doesn't work, on differents datacenter. I suspected Firewall issue, but finally, with "all opened", it is still not working.

I'm using bbb via docker ( as https://github.com/bigbluebutton/docker ) I encountered the webrtc sfu error as described here : https://github.com/bigbluebutton/docker/issues/226 So I changed mediasoup version to 3.10.3

When opening a room, when choice the audio method, it cannot connect with (raison=ICE error) (erreur 1004)

On server side I got this log on webrtc_sfu:

BTW, when using docker-compose I got : WARNING: Some services (jodconverter) use the 'deploy' key, which will be ignored. Compose does not support 'deploy' configuration - usedocker stack deployto deploy to a swarm. Maybe, i'ts not a relevant ?..

Using up to date server Debian (tried with ubuntu), client is firefox or chrome.

If some one have an idea.. thanks by advance.

hello, Is somebody have a solution for this issue ?

[mricim]

Same problem, same error... With the camera I get the error 2200

[leonidas-o]

Same issue with the microphone and webcam share here. This issue is open since August 2022 and has no reply yet, is someone actually even taking care of all the open issues here?

Me too same Issue with the microphone and webcam. I found this error in the log : [ERR] switch_core_media.c:9795 AUDIO RTP REPORTS ERROR: [Bind Error! PUBLIC_IP:19146] I disable Firewall and I redirect port in router. How can we diagnostic this?

[leonidas-o]

Couldn't make BigBlueButton work behind a NAT, with opnsense/pfsense 1:1 NAT + Reflection etc., so I gave up on that approach. I still found a solution assigning the second public IP to the BBB VM, which I documented here: https://serverfault.com/questions/1121061/assigned-second-public-ip-to-vm-from-outside-not-reachable/1121266#1121266

Thanks for sharing this @leonidas-o.

I have the same issue and see in the network trace of my browser in the websocket to the PBX (/ws?sessionToken=XXX) the following error:

Digging into the freeswitch log with

docker compose logs freeswitch -f

I got the following error:

bbb-freeswitch  | [ERR] switch_core_media.c:9638 AUDIO RTP REPORTS ERROR: [Bind Error! x.x.x.x:22112]

update: I have now added the reserved ports as suggested in https://github.com/signalwire/freeswitch/issues/1987 but it didn't help :-(

Anyone else having this issue?

[pkolmann]

I just fixed this issue for me.

I saw in the freeswitch log, that freeswitch wants to bind to the external NATed IP address, but this IP was not available.

So I followed https://github.com/bigbluebutton/docker/blob/develop/docs/behind-nat.md and added the external NATed IP to my server as second IP and now freeswitch can bind and is happy and I have audio!

Hope this helps others as well...
