Audio and Video doesn't work in Android APP

Hi,

I’ve installed and configured a Jitsi On Premise server with a SSL cert non self-signed, it works ok with web browser on PC, even using an Android app called “My Jitsi Meet”(https://play.google.com/store/apps/details?id=com.mobileappware.myjitsimeet&hl=en&gl=US it’s not the official) it works well with audio and video, but with the official app of Jitsi Meet (https://play.google.com/store/apps/details?id=org.jitsi.meet&hl=en&gl=US) the audio and video doesn’t work, the participant on mobile can’t watch nor listen anybody, and the other particpants can’t watch nor listen to android users.

Is there any configuration can help me to solve it?

Probably something to do with your chain cert. Check:

already did, now the state is Correct, but the same problem
