Bridge Channel send: no opened channel

Hi,
I had a working setup with one jitsi meet server and multiple VBs, everything was working very well with no changes in any configuration.

Now I am getting this errors and now call more than 2 is working which means the bridges has some issues. Now I didn’t see this error before, Any ideas on how to fix that or even debugs.

thank you

This means that there is no data channel opened, you can check jvb logs, do you see any errors?
