Mysteries "Remote end closed connection without response" - How to deal with it?

Sometimes my bot fails simply fetching balance details although the internet connection is fine.

import os
from pathlib import Path
from binance.client import Client

client = Client(
    api_key='<your api key>',
    private_key=Path(
        os.path.dirname(os.path.realpath(__file__)),
        'your-prv-key.pem'
    )
)

# possibly wait for hours or days

client.get_asset_balance(asset='USDT')['free']

Traceback (most recent call last):

This is bad, cz some strategies calculate signals rather rare and if it then can't open a position, it impacts overall performance. What's the best way to deal with it?
