@FreePietje Cool. So I followed this tutorial: https://invidious.snopyta.org/watch?v=-0M0NeZ_cU4 -- which worked fine. I had a slight issue with DNS records not being correct, but that was more my mistake I think (entering values slightly incorrectly). Everything is working now and I'm in the process of trying OMEMO (for E2E encryption). I think this is only possible for 1-2-1 chats. I'm using Pidgin client for Debian and Conversations app for LineageOS.
