It works fine on my device.

You have some other process that has locked your sqlite database (or the database is corrupted) Try deleting the database file or moving it somewhere else so that it can be recreated.

As far as I know, you need to log in into Telegram to use telethon. In your machine you can do it with command line interface, but in hosting you can't. I solved this problem when rent a virtual server, where I can log in Telegram. Then I just run python script with some options in order to always working
