Jibri recording shows dummy participant in the room when I block location "/" at nginx


I am facing some different issue on my jitsi meeting server with jibri.

I need to block direct call to https://meet.raghavaa.com/, so I blocked location = / at nginx.

But after this, I see jibri showing recording participant in the room. Then I enabled location=/ back again.

Later on I understood, jibri is hitting “/” first then actual meeting /91js5xxxee .

Any idea how to stop jibri to hit “/” so that I can block https://meet.raghavaa.com/

Please help.
