discord.errors.ConnectionClosed: Shard ID None WebSocket closed with 1000

[YungPingXu]

I run my discord.py bot on my win11 desktop computer 24/7.
However, the following error occurred once in a while.

Attempting a reconnect in 0.30s
Traceback (most recent call last):
File "venv\lib\site-packages\discord\client.py", line 659, in connect
await self.ws.poll_event()
File "venv\lib\site-packages\discord\gateway.py", line 646, in poll_event
raise ConnectionClosed(self.socket, shard_id=self.shard_id, code=code) from None
discord.errors.ConnectionClosed: Shard ID None WebSocket closed with 1000

This error does not affect the program and the program is still running normally, but I want to ignore or catch this error message.
Does anyone know how to ignore or catch the above error?
Thanks~
