Strange Behaviour Jitsi Meet Android App

Android App Jitsi Meet Strange Behaviour

Hello Everyone;
I am facing a very strange issue using Jitsi Meet android app. After installation when i configure my server “https://paknetworks.com/” in settings and try to join a room I face infinite loop of “Rejoin or Cancel” and unable to join the room.
But if i open my server link i.e. http://www.paknetworks.com/ in the browser and click “Go” after writing room name it asks to open the link in App, i click on “Download App” even it is already installed and it works. Room asks for the authentication and upon providing right credentials it let me in. I have aloso tried by putting full URL of server and room in the room textbox but that also didn’t work.you may use user "fsd@paknetworks.com" with “abc123” as password to test this whole scenario.

Prompt action would be highly appreciable.

Kind regards;
Adnan Alam.

Does anyone help here?
