Well, so as some of you could already noticed, there was server bug preventing users from logging in and probably also creating accounts etc.

That was some stupid mistake in my library and it should be hopefully already fixed on server side (so no need to download client again).

I forgot to add database connection validity check before operations on database and since idle connections are terminated after long enough inactivity, server was left without database connection (actually with invalid database connection, server still thought connection exists, but it always failed), so all DB related operations miserably failed whenever possible (and what is even worse, whenever required!).

Aaaand, I'm happy that happened, because that's why I published this project! To find such cases I haven't found during my own tests. In real live use-cases some scenarios may be common, but when doing dev test you just never think about them, so they are left unnoticed and possibly could happen very often during real operation...

Anyway, this database issue should be already resolved, so you can try creating account/logging in again if it failed before with error like "check your credentials" or "server unavailable".
