Hi stepan4,
you had just ONE disconnection on March 27. (you can see that on your profile.)
There are also many posts on the forum on how to tackle connection problems that already helped several players.
Here’s one of them:

Wth 3000+ users playing at the same time it’s possible that some of them don’t have the fastest or most reliable Internet connection.
If it was the server, all of us would have the same problem.
(I’m not talking about the issue with the Hungarian telecom a few weeks ago that affected Hungarian players only and which has been fixed by now.)
Have a nice day and good games!
