Stops recieving messages after 10-20 hours

[AustinTurney]

Code that causes the issue

async def main():
    await client.start(phone=phone_number)  # Start the client
    print("Listening for messages...")
    await client.run_until_disconnected()  # Keep the client running   

if __name__ == "__main__":
    import asyncio
    asyncio.run(main())

Expected behavior

The program would run until disconnected or user interrupted

Actual behavior

after 10-20h the program stop logging messages. I then have to manually interrupt the program and restart the script.

I use telethon for 24/7 monitoring of specific telegram channels, have not encountered any problems yet. Here is my code:

from telethon import TelegramClient, events

# Create a Telegram client
client = TelegramClient(SESSION_NAME, API_ID, API_HASH)

async def main():
    print("Starting Telegram client...")
    await client.start()
    await client.run_until_disconnected()
    
if __name__ == "__main__":
    import asyncio
    asyncio.run(main())
    
@client.on(events.NewMessage())
async def new_message_handler(event):
    #Your program goes here
