Connection are forcefully closed 10054

My alpaca connection was closed forcefully by error code 10054.
The exception is
requests.exceptions.ConnectionError: (‘Connection aborted.’, ConnectionResetError(10054, ‘An existing connection was forcibly closed by the remote host’, None, 10054, None))

and I could not connect again after the failure.

I can’t log in either. This happened the other day too. Hopefully this can be fixed soon.
