Unexpected error with JVB in datachannel mode

Hello! Need your help very much. I have a few small projects, which use Jitsi Meet API and Jitsi Meet Videobridge (not self-hosted) with ‘datachannel’ option. Yesterday all were ok, but I started use this projects today and got this errors:
“Bridge Channel send: no open channel”.

No code changes, no browser version changes.
What is the reason? Can it be linked with last commits in the official jitsi repo?

You are using meet.jit.si and you are passing openBridgeChannel: 'datachannel' when opening meetings?

Thanks for your answer!
Yes. I use parameters like this:

const connectionOptions = {
    hosts: {
        domain: 'meet.jit.si',
        muc: 'conference.meet.jit.si',
        focus: 'focus.meet.jit.si',
    serviceUrl: 'https://meet.jit.si/http-bind?room=' + room,
    clientNode: 'http://jitsi.org/jitsimeet',
    useStunTurn: true,
    useTurnUdp: false


const conferenceOptions = {
    openBridgeChannel: true // or 'datachannel'

You should not use datachannel, we are moving away from it in favor of websockets and as part of that meet.jit.si no longer supports it at all.

Oh, thanks! So maybe you can recommend me a way how to send text messages using jitsi and only WebRTC protocol?
As I see, sending texts uses JVB. Can I use TURN for it and only WebRTC?

Are you using iframe API or lib-jitsi-meet? If you are using lib-jitsi-meet you should get what’s in meet.jit.si config: https://meet.jit.si/config.js
You should be passing openBridgeChannel: 'websocket'
If using the iframe you should not be passing that …

I’m using lib-jitisi-meet. The main question is can I send text messages to another user without using bridge channel?
