I have a autobahn twisted websocket running in python which is working in a dev vm correctly but I have been unable to get working when the server is running in openshift.

Here is the shortened code which works for me in a vm.

from autobahn.twisted.websocket import WebSocketServerProtocol, WebSocketServerFactory, listenWS
from autobahn.twisted.resource import WebSocketResource

class MyServerProtocol(WebSocketServerProtocol):
    def onConnect(self, request):
        stuff...
    def onOpen(self):
        stuff...
    def onMessage(self,payload):
        stuff...


factory = WebSocketServerFactory(u"ws://0.0.0.0:8080")
factory.protocol = MyServerProtocol
resource = WebSocketResource(factory)

root = File(".")
root.putChild(b"ws", resource)
site = Site(root)

reactor.listenTCP(8080, site)
reactor.run()

The connection part of the client is as follows:

var wsuri;
var hostname = window.document.location.hostname;
wsuri = "ws://" + hostname + ":8080/ws";

if ("WebSocket" in window) {
    sock = new WebSocket(wsuri);
} else if ("MozWebSocket" in window) {
    sock = new MozWebSocket(wsuri);
} else {
    log("Browser does not support WebSocket!");
    window.location = "http://autobahn.ws/unsupportedbrowser";
}

The openshift configuration is as follows:

1 pod running with app.py listening on port 8080 tls not enabled I have a non-tls route 8080 > 8080.

Firefox gives the following message in the console:

Firefox can’t establish a connection to the server at ws://openshiftprovidedurl.net:8080/ws.

when I use wscat to connect to the websocket.

wscat -c ws://openshiftprovidedurl.net/ws

I get the following error:

error: Error: unexpected server response (400)

and the application log in openshift shows the following:

2018-04-03 01:14:24+0000 [-] failing WebSocket opening handshake ('missing port in HTTP Host header 'openshiftprovidedurl.net' and server runs on non-standard port 8080 (wss = False)')
2018-04-03 01:14:24+0000 [-] dropping connection to peer tcp4:173.21.2.1:38940 with abort=False: missing port in HTTP Host header 'openshiftprovidedurl.net' and server runs on non-standard port 8080 (wss = False)
2018-04-03 01:14:24+0000 [-] WebSocket connection closed: connection was closed uncleanly (missing port in HTTP Host header 'openshiftprovidedurl.net' and server runs on non-standard port 8080 (wss = False))

Any assistance would be appreciated!
