Hello.
I am an active player on the official Minecraft game servers.
From today, I have a problem.

I have stopped accessing servers that require the official version of the game, although a licensed copy is already available.

I studied this topic, and I'm not the only one with this problem.
In that article it is written that you should contact the game support service.

(Problem on all versions)

  A photo of the error is attached below.
 I can provide all evidence.
