nginx websocket proxy about channels

[andrewgodwin]

Does the connection work from your browser directly? Would be good to establish that it works without the proxy in the way; might be a browser-specific bug as well.

That said, the current runwsserver code is being retired in favour of an all-combined HTTP+WebSocket server, which you can try out with runallserver right now, but that's still under development so it might not work (but might give a different error, or might work?)

I found the culprit. It looks like specifying the ws:// url for WebSocketServerFactory is optional. If specified autobahn will check if the header in the connection matches.

the code for that in autobahn is at : https://github.com/crossbario/autobahn-python/blob/a771b54bc93f4d0cc273162dc737f2c528a92fdd/autobahn/websocket/protocol.py#L2508

by removing the url at https://github.com/andrewgodwin/channels/blob/master/channels/interfaces/websocket_asyncio.py#L23 my errors goes away and it looks like everything is working now.

Fantastic, thanks for investigating - will remove that now.
