Upgraded Prosody from 0.10.0 to 0.11.5.

   sudo apt-get update
   sudo apt-get install prosody

I need the recent prosody version because some events are not available in the 0.10.0 version. Had upgraded another install with no issues before.
changed storage from ‘none’ to ‘memory’

I can connect to the welcome page and create a new room. I can log into the room with the credentials provided. After about 15 seconds, the client disconnects and tries to reconnect again. (in a loop)

I have found a similar post [jitsi-users] health-check timed out, Can not invite participant -- no bridge available and checked the system clock. there is no issue with Date/Time as described in the post.

Anyone any idea what is going wrong?

here is the console.log from Chrome

meet.mydomain.tld-1593417798366.log (97.8 KB)

This means there is not enough memory for jicofo to run. The default configuration is it to use up to 3GB of memory. https://github.com/jitsi/jicofo/blob/master/resources/jicofo.sh#L31

Well, I have seen that.
The machine has 16GB and according to the free command, there are 15GB available.
