Room crash help!

hi all, i just installed the jitsi meet fallowing the docs,
when users join the meet the room crash, i saw F12 dev options and i see colibri something related to password 403 response, the users are in room but the mic and camera dont work,

Do you see the same when you do a 3 tab call using jitsi-meet?

yes, i tested with more than 3 users too, when i open the metting work and after few seconds the room crash

i used latest ubuntu OS version

Everything is running on one machine right?
Do you have this in your nginx config: jitsi-meet/jitsi-meet.example at a6ce4fe3680f6191948720c3658ab8412752de1b · jitsi/jitsi-meet · GitHub

Maybe check nginx logs for errors.
