Can't connect to socket.io server: unexpected status code 404

First off, thanks for writing this python library; it's a life-saver for my project.

I'm trying to connect to the [IEX websocket server](https://www.iextrading.com/developer/docs/#tops) using this library with the example code (slightly modified):

```
from socketIO_client import SocketIO, BaseNamespace
import logging
logging.getLogger('socketIO-client').setLevel(logging.DEBUG)
logging.basicConfig()

from socketIO_client import SocketIO, LoggingNamespace

def on_connect():
socketIO.emit('subscribe','snap')

def on_disconnect():
print('disconnect')

def on_reconnect():
print('reconnect')

socketIO = SocketIO('https://ws-api.iextrading.com/1.0', Namespace=LoggingNamespace, wait_for_connection=True, resource='last')
socketIO.on('connect', on_connect)
socketIO.on('disconnect', on_disconnect)
socketIO.on('reconnect', on_reconnect)
```
However every time I run this, I run into the following error:

```
WARNING:socketIO-client:ws-api.iextrading.com:443/1.0/tops [engine.io waiting for connection] unexpected status code (404

)

```

The URL works fine on the javascript client:
```
const url = 'https://ws-api.iextrading.com:443/1.0/tops'
const socket = require('socket.io-client')(url)

socket.on('connect', () => {
socket.emit('subscribe', 'snap')
})
```
How can I fix this issue? Does it have something to do with the commented out HTML?
