Проблема с учётной записью xbox

Could you please translate this to English, as most of the community are English speakers, you'll have a better chance to get help.

Я хочу узнать, что мне делать в такой ситуации, к кому обращаться. Аккаунт не новый, 3 года ему, именно в WoT

Okay.

Subject: Problem with an account in the World of Tanks Console

This problem appeared in April this year. The essence of the problem is this: I'm trying to log in to the official site of the console version of WoT https://console.worldoftanks.com in my account, but instead of authorization, I get the following message:

Login failed

There was a problem communicating with your authentication provider. Please check to make sure you have used the proper credentials. If the problem persists, try again later or contact our Player
Support.

I contacted the representative of the console version and that's what he wrote to me:

Generally. I was told that the APIShka and all logins are made by the Maikov. Write to them and ask what's up. Let them give a detailed answer.

If you send, then we will put a bug. Without a confirmation of the microsoft, this can not be done.

That is, it's not from the side of the game itself, but from Microsoft. I can not just authorize myself on the site, I could play the game, but use the site - why not

I want to know what to do in this situation, who to contact. The account is not new, 3 years old to him, it is in WoT

Дело в том что я могу зайти с учетной записью моего брата,а вот со своей нет.Я думаю если бы провайдер блокировал доступ,то я бы не смог зайти ни с одной учетной записью

[Translation-

The fact is that I can log in with my brother’s account, but not with my own. I think if the provider blocked access, then I wouldn’t be able to log in with any account]

Мммммм, включить X-box 360 и зайти с него ...

В чем проблема при входе с самой приставки-то?
