Hi Sahid,
thanks for your great example! When I execute it I get the error
socket.error: [Errno 111] Connection refused
How do I debug this? Did I miss a configuration?
./lazyclient.py
ws://127.0.0.1:6083/?token=39262891-2588-4872-994b-3be9b7333fd7
Traceback (most recent call last):
File "./lazyclient.py", line 27, in <module>
ws.connect()
File "/usr/local/lib/python2.7/dist-packages/ws4py/client/__init__.py",
line 209, in connect
self.sock.connect(self.bind_addr)
File "/usr/lib/python2.7/socket.py", line 224, in meth
return getattr(self._sock,name)(*args)
socket.error: [Errno 111] Connection refused
