The server has encountered some issues recently and the devs are working on it. Unfortunately we do not have an eta on when they will be back up atm.

I also cannot log in

Не могу зайти что делать?

I'm now getting something that seems like a similar error aswell.
But if it is a server issue why does the uptime website say "all systems operational"

@pa4sam
Either devs were very fast in fixing the problem (in which case thanks!) or it randomly resolved itself.
I can now log in without any issues.
