New Setup - EndpointMessageTransport.log() SCTP

Hello,
I have a new setup Jisti with docker and use docker-compose.yml and .env (With url parameter).
No video and I have this error in log :

jvb_1 | JVB 2019-12-16 22:36:18.956 WARNING: [25] org.jitsi.videobridge.EndpointMessageTransport.log() SCTP connection with c044d1725a685a0b not ready yet.
jvb_1 | JVB 2019-12-16 22:36:18.956 WARNING: [25] org.jitsi.videobridge.EndpointMessageTransport.log() No available transport channel, can’t send a message

an idea
Tks

That message is most likely harmless. What do you see in the JS console?
