Browser fails to open 'https://localhost:443/tests/websocket.html'

[KrrishnaShah]

After following step up to 3 in the section 'TLS/SSL Example'

FIY: both the servers are running i.e.

python tests/simple_https_server.py
and
python tests/example_server.py --example chat --ssl 1

but no response

I also tried to connect wss with ws client (i.e. 'WebSocket Test Client' a google chrome extension)
but it throws 'error'

Someone please guide me on 'how to connect wss client with this server' .......
