Lobby feature not working after upgrade


I upgraded jitsi to the latest version but lobby feature is not working. we dont ses it under security options. I tried everything like moving the required configuration in prosody config file from virtual host “guest.domain” to “main domain”. In that case lobby is not working also we are having another problem about authentication. It is starting not to ask password to create a conference. What do you think is the problem?
Could you please share default complete meet.domain.cfg.lua file?
For example do i need to create a virtual host command line for the guest.domain?
Thanks and regards.

thanks but it was solved by adding virtual host line for guest domain. I deleted completely before. because i don’t enable any feature in it. I see i need to add it even if it is empty.
