unable to login to lemmy.ml using 1.0.152

I believe 1.0.152 is meant to be the version compatible with the new Lemmy release, and it works pretty well as a guest user. Unfortunately, when I try to login to lemmy.ml (which uses the new server version), I get Error: An unknown error has occurred.

Looked through the app and didn’t see any official bug report area mentioned, so I hope this is the right place to go for this. If not, sorry for the noise!
