How to log in to telethon in other ways?

Question

Python

I am using paid host pythonanywhete.
I am running file with telethon client.
Asks for a number.
I enter.
Asks for a code.
The code does not come, no matter how much I wait.
Then I logged in on my computer, the code came.
But I can’t run this file on the hosting, because the code doesn’t come!
Why is this, or how to rush?
Can someone help?
