Bot goes offline after 10-20secs

[developers192]

Hello. I'm a new user just started writing bots with discord.py. Recently I've written a ModMail bot. When i try running the bot, it does get online and responds to commands, as expected. But after 10-20 seconds, the bot goes offline but the python file in my pc still running, no errors in console. Can anyone help me with this?
My bot's code: https://pastebin.com/SDWjf8Rb (Token removed)
Sorry for my messy code arrangements.

EDIT: Here's my bot log

You have the event loop blocked because of your use of the with context manager without yielding from it.

There will also be issues because you define and start tasks inside of on_ready and changing presence every 4 seconds.

As for your immediate issue, consider using a database to store data persistently.

Thanks for your reply, I will look into it.

The existence of a with does not mean the code is being blocked. There are, presumably, some non-async context managers that can block but I see none here.

The first time a message is sent a while True loop is started, and reads a line from a file... then does things based on that. If those ifs do not pass then it will permanently block since those are the only asynchronous things I see in this while loop. That's where the issue is I would bet

Thanks for your response! I added a if not line: return and it fixed the issue!
