Issue with Cloudflare Connection

hello,

I have installed jitsi and integrate that domain with Cloudflare and it was working fine.

but before few days I have updated my jitsi version, after then it not working properly.
App URL: https://immerch.co/

if I disabled Cloudflare, then it requests direct come to my host server and it’s working fine. but when I enabled it, Cloudflare cannot get a response back from the Host server.

I have tried with new fresh installation as well but still same issue.

if I start my old instance and configure it with Cloudflare then it’s working fine…but there something wrong with new installation or update version.
