Hi @KolyaManushka,
Unfortunately it appears that you are running into a current known Server Error issue, which appears to be affecting players (at least primarily) in Russia, Latvia and Sweden.
What ISP do you use?
We’ve reached out to our Backend Service Provider who are now investigating into the issue, and we’re waiting for an update from them.
Unfortunately, I don’t have an immediate solution for you, but rest assured we are on the case.
You can view other threads on this issue, where we’ll be posting any updates, here:
