Attempts to connect to corporate jitsi server with Android app always receive an immediate disconnect when trying to create/join a conference.
It would appear from other similar posts that this is a certificate trust issue, but I am unable to verify that and can find no way to test to determine what the app is seeing as a problem.
I have installed Jitsi on a local corporate server (Ubuntu 18.04 LTS). I deployed it using corporate certificates and have installed the corporate CA on all corporate devices. I have validated the trust chain for the certificates used to deploy Jitsi.
Jitsi runs without issues for browsers (Mac, Windows, Linux, Chrome, Firefox, and Safari); Runs fine with the Jitsi app on IOS 13. Even the chrome browser on the Android device accepts the connection as valid and then transfers control to the jitsi app where it now fails to connect.
The root CA is installed on the Android device as a User Cert, and the nginx certificate used for the web site includes the full-chain certificate. The certificate uses Subject Alternative names to identify the server.
Any suggestions for troubleshooting this or insights as to the source of the problem would be appreciated. At this point we are able to use the server with everything except Android devices.
