WebSocketApp connection not closing as expected

[Juliet-Kahofer]

I have inherited a program that makes a websocket connection to a server, reads messages from a queue then closes:

    print("Starting the retreiving process")
    ws = websocket.WebSocketApp(ws_url,
                                header={'authorization':'Basic ' + auth},
                                on_message=on_message,
                                on_error=on_error,
                                on_close=on_close)
                                #if error exit
    print("Connected to websocket")
    ws.on_open = on_open
    wst=threading.Thread(target=ws.run_forever)
    print("Starting the retreiving process")
    wst.start()
    time.sleep(float(active_time))
    ws.keep_running=False
    wst.join()

This was working fine for us. However, I've had to amend the Thread line as follows, to stop the connection carrying out SSL certificate checks:
wst=threading.Thread(target=ws.run_forever(sslopt={"cert_reqs": ssl.CERT_NONE}))

The program now successfully makes a connection to the server but never closes.
I've tried explicitly closing the connection with ws.close(), but no luck.

Two questions:

• is this expected behaviour - i.e. does bypassing ssl certificate checks mean that the connection will not close?
• how can I force the connection to close (after active_time seconds)?

1. No, this is not expected. The only logic that should be associated with this cert_reqs value are in _wrap_sni_socket in _http.py
2. You can use a ping_timeout to close the connection if there is no response from the server after a certain time. If you want to close the connection even though the server is responding, you should handle it in on_message or a similar callback.

Please make sure you are using the latest version of the library and consider checking issues #612 and #592 related to closing a connection.
