I cannot see current rank in realtime on my screen(see screenshot)
Just looks like Rank: - and Getting player list... and so on.
How can I help working this?
This is because you are in a Contest.
Contests do no count in the competition for global points. Usually, there are few player playing at the same time.
You can see your rank and points here on WWW by clicking on the contest. For example Abeta Binter Contest.
This can happen in other situations for regular puzzles as well: when you play offline or when you just started a new puzzle (several minutes are needed for rank update).
For all puzzles / contests this keep happens, even if I wait for refresh...
Looks like something is weird on server?

It could be a bug (not from server but from the way the server is communicating with your client). Because for most of us, it works well. May be linked to some specific environment.
