registration stopped to work

I try to register user as usually with backendless.userService registering:user response: and get the error “fail userService_registerUser, error = Не удалось найти сервер с указанным именем хоста.”

Hello, Pavel!
Unfortunately, we can’t reproduce this issue.
Can you please try again and confirm that the problem still exists?
It would be great if you can check it on other device.

regards, Alex

Здравствуйте, Павел,
Ошибка свидетельствует о том, что у приложения проблемы с сетью (например, отсутствует подключение к Интернету).

sorry, the problem is with our server (I forget that we use it when making registration)
