Network errors with Python Telegram Bot

Question

I use a Python Telegram Bot script in Visual Studio Code on my PC, and sometimes i have this error:

telegram.ext.dispatcher - ERROR - No error handlers are registered, logging exception. Traceback (most recent call last):
connectionpool.py", line 614, in urlopen httplib_response = self._make_request(conn, method, url,
connectionpool.py", line 402, in _make_request six.raise_from(e, None)

ssl.py", line 1099, in read return self._sslobj.read(len, buffer)
ConnectionResetError: [WinError 10054]


telegram.error.NetworkError: urllib3 HTTPError ('Connection aborted.', ConnectionResetError(10054, "Connessione in corso interrotta forzatamente dall'host remoto", None, 10054, None))

I follow this link and i tried to modify the updater in this way, but the problem persists:

updater = Updater(token='MYTOKEN', use_context=True, request_kwargs={'read_timeout': 6, 'connect_timeout': 7})

Running the script on my Android phone with 4G connetion, i haven't this error. So i think is my ADSL connection, maybe not stable.

What can i try to resolve this problem? Maybe modify some parameters in the updater?
