No reconnection after WAN disconnection

[bachya]

I'm having an issue where uses of my package (which utilizes python-socketio) notice that after an abrupt WAN disconnection, python-socketio doesn't reconnect. This is the traceback they notice:

  File "/usr/local/lib/python3.7/site-packages/socketio/asyncio_client.py", line 102, in connect
    engineio_path=socketio_path)
  File "/usr/local/lib/python3.7/site-packages/engineio/asyncio_client.py", line 73, in connect
    url, headers, engineio_path)
  File "/usr/local/lib/python3.7/site-packages/engineio/asyncio_client.py", line 250, in _connect_websocket
    extra_headers=headers)
  File "/usr/local/lib/python3.7/site-packages/websockets/py35/client.py", line 12, in __await_impl__
    transport, protocol = await self._creating_connection
  File "uvloop/loop.pyx", line 1846, in create_connection
socket.gaierror: [Errno -3] Try again

Versions:

python-engineio                  3.8.2.post1
python-socketio                  4.2.0

This may not be a bug – it may be an error in my own understanding – but wanted to open an issue to get your advice. Thanks!

@bachya Yeah, this is a connection error that I'm not catching. I expected the WebSocket connection errors would be exceptions from the websockets package, but it looks like for this particular condition they just allow this lower level error to bubble up.

Thank you!
