All TG sessions termination

[ssomebodyss]

Hi, everyone. I wanted to try this project for files uploading but once passed authentication with api_id and api_hash successfully all devices's and app's sessions connected with the corresponding phone number were automatically terminated after a small period of time and any TU action required re-auth. The only way to get them back is passing registration from the mobile app again. Repeating the same auth steps for TU causes the same result again and again.
Did you face anything similar?

WBR.
