No available transport channel, can't send a message

After I updated jitsi a conference is not working anymore.
I get the message, that somethin went wrong and I can find the following message in the logs:

JVB 2019-09-06 13:36:28.452 WARNUNG: [13] org.jitsi.videobridge.EndpointMessageTransport.log() SCTP connection with 26e23beb03dac87a not ready yet.
JVB 2019-09-06 13:36:28.453 WARNUNG: [13] org.jitsi.videobridge.EndpointMessageTransport.log() No available transport channel, can’t send a message

What happened?
Disclaimer:
This machine has not NAT.

Hi, same for me here. Do you resolved it? Ubuntu 18.04 working for months, now when someone join conference I got fail loop. Now clean install of ubuntu and jitsi-meet package from repository and fail loop again.

This is jvb.log

Help please. Sorry for my english.

no, sorry.
I didn’t

Editing hosts file. Change localhost for jitsisrv (without domain.xxx) then clean install from repo package did the trick!

Wrong. It worked for 5 minutes the began to loop again when number 2 member enter conference.

Partially solved.

Something very strange happens. I had to edit the Jicofo config file.
JICOFO_HOST = localhost changed for jitsisrv (in my case).
Restart jicofo

This worked until I restarted the jitsi-videobridge service or rebooting.

Then if I re-edited the Jicofo config file and changed it again from jitsisrv to localhost and then restarted Jicofo the videoconference worked correctly until the computer restarts.

Weird

This worked for me, too.
Strange behaviour

Also i installed jitsi fresh on a Debian 10
I still face this problem.
