Secore Domain: Endless login prompt for new room

Hi,

I upgraded jitsi-meet to latest version 2.0.4627-1 from https://download.jitsi.org stable/ Packages on my Ubuntu 18.04.4 LTS system.

Further I have a secure domain setup according to description jitsi.github.io/handbook/docs/devops-guide/secure-domain.

After the upgrade I get an endless loop for login to create a new room. User and password are correct, but no new room is created Jitsi Meet prompt again for user name and password.

The prosody version is 0.10.0-1build1

In prosody.log I found that BOSH client is immediately disconnected:

May 31 17:24:47 mod_bosh info New BOSH session, assigned it sid ‘f2177a80-99ec-4149-9448-5a2bb357fc0c’
May 31 17:24:48 boshf2177a80-99ec-4149-9448-5a2bb357fc0c info Authenticated as user@my-host
May 31 17:24:48 boshf2177a80-99ec-4149-9448-5a2bb357fc0c info BOSH client disconnected

Please note the user authentication works before upgrade of Jitsi Meet.

What goes wrong? Where in log information I will find more about reason for the endless login loop?

prosody.err, jicofo.log.
FTR I upgraded today and secure domain works still without problem.
