Can’t connect to Dota 2 after register on FaceIT


My steam profile is public at all check-boxes, 1000+ hours played DotA 2, no VAC-bans too. When I tried to connect error alert is "Во время регистрации произошла непредвиденная ошибка. Если проблема не исчезнет, свяжитесь со службой поддержки. " (Unknown Error on register. Please text to support.)
