Can't login anymore

Hi there, first of all: Thanks for the super useful app!

Unfortunately I can't login anymore for some time; using the anonymous login gives me a "No network connection" error and trying with my own credentials just causes the progress dialog to popup for a very brief (< 100ms) amount of time, only to be closed again without any kind of feedback.

I can't paste log output right now but I can attach it later if needed. I'm using 2.0.5-beta, and cleared all app data. I'm on Android 9, using the Syberia ROM for Xiaomi Mi 5 w/ microG.
