Unable to connect to default server on LineageOS with MicroG

I installed the Jitsi Meet app on my phone which is running LineageOS with MicroG (a FOSS Google Play Services replacement). I haven’t changed any settings in the app, and when I join a room, I immediately receive a message reading “You have been disconnected. You may want to check your network connection. Reconnecting you in xx sec …”.

On the off chance that anyone on this forum is using my setup, how did you get Jitsi to work?

Otherwise, I tried to do some troubleshooting of my own but I couldn’t find any error logs in the app’s files. I guess some service is failing but I have no idea which.

Does anyone have any idea what might be going wrong or any ways I could get the app to tell more more about why this is failing?
