Jitsi meet installation step

Hi guys,
It’s my first time in this community. I finish to install my server on debian buster by following the quick install “https://github.com/jitsi/jitsi-meet/blob/master/doc/quick-install.md”. I can create a room but it’s impossible to join it, it’s said “something wrong”

.

May be i forget some step, if someone can help me
