Telethon после конвертации тдаты выдает странную ошибку?

[blackrtruth]

The server claims it doesn’t know about the authorization key (session file) currently being used. This might be because it either has never seen this authorization key, or it used to know about the authorization key but has forgotten it, either temporarily or permanently (possibly due to server errors).
Вот такая ошибка. Причем она появляется только на части тдат, которые конвертируются по одному принципу

do you have access by the official client telegram?
check the sessions opened in configurations, the session must have been closed.
