Example app crashes upon login

[YesThatGy]

Trying to connect to our own Prosody-based XMPP/muc server. Other clients work fine with it.

Any attempt to connect with credentials for an account cause it to crash almost immediately on the Android VM running under AndroidStudio on Fedora Linux. Below please find the debug log from AndroidStudio:
