WebSocket connection upgrade failed (403 - Forbidden)

vijoeyz

I am facing this problem after upgrading to kiteconnect 3.9.5:

WebSocket connection upgrade failed (403 - Forbidden)

From the previous forum discussions (here and here), I understand that problem occurs if incorrect access_token is used. However, this has never been a problem until I upgraded to 3.9.5, and the same program ran without any problems ever in the previous version, 3.8.1!

Is there a backend problem with my account/keys?

@sujith @rakeshr
Quick help on this is appreciated since I have high stakes. Thank you.

vijoeyz

And the code has always been this:

def init_ticker(api_key, access_token):
    try:

        kd.kws = KiteTicker(api_key, access_token, reconnect_max_delay=5, reconnect_max_tries=300, debug = True)

        kd.kws.on_ticks = on_ticks
        kd.kws.on_close = on_close
        kd.kws.on_error = on_error
        kd.kws.on_message = on_message
        kd.kws.on_connect = on_connect
        kd.kws.on_reconnect = on_reconnect
        kd.kws.on_noreconnect = on_noreconnect
        kd.kws.on_order_update = on_order_update

        # Infinite loop on the main thread. Nothing after this will run.
        # You have to use the pre-defined callbacks to manage subscriptions.
        kd.kws.connect(threaded = True)

        # Block main thread
        #logging.info("This is main TICKER thread.")

    except Exception as e:
        exc_type, exc_obj, exc_tb = sys.exc_info()
        log.console('%s: init_ticker, %d: %s' % (kd.current_time, exc_tb.tb_lineno, str(e)))


def get_kite_client():
    global kite_client

    kite_client = KiteConnect(api_key = kite_api_key, debug = True)

    if "access_token" in session:
        kite_client.set_access_token(session["access_token"])

    return kite_client



@app.route("/login")
def login():
    global kite_client

    try:
        request_token = request.args.get("request_token")

        kite_client = get_kite_client()
        data = kite_client.generate_session(request_token, api_secret = kite_api_secret)
        kite_client.set_access_token(data['access_token'])

        session['access_token'] = data['access_token']

        init_ticker(kite_api_key, data['access_token'])

@vijoeyz
v3.9.5 has breaking changes. You need to upgrade to a stable version v4.0.0. The same was announced here.
You can upgrade using pip install --upgrade kiteconnect

vijoeyz

I will do that. Meanwhile, I got to know that the ticker field name changes, and have already incorporated. Thanks.

@rakeshr



I just upgraded to 4.0.0, but this 403 problem still persists.

@rakeshr

Please let me know if you need more data. You may appreciate my urgency. I have also tried connect(threaded = True, disable_ssl_verification = True) without success.

Thank you...

rakeshr

We haven't done any changes from our side. Also, I just tried a similar websocket code flow at my end as you stated above, and it's working perfectly fine.
Are you able to make other API calls using same access_token? Like order book, portfolio fetch, etc?

vijoeyz

Actually now that mentioned, yes, I can see my positions() and fetch order book!

vijoeyz

@rakeshr I understand the logic of you haven't made any changes. It applies to me as well: I haven't made any change at all. This has been smooth for >2 years!

Why connection requested is being rejected now, after the upgrade? Give me a clue and I can try figuring it out.

vijoeyz

I can IM you if you need private data to debug.

rakeshr

I don't see any issue in your WebSocket code, except for the access token. Can you re-generate the access token and check again?
Also, print access_token while making API requests and subscribing to Websocket and compare, if both are the same.

rakeshr

If still facing the issue, you need to print the socket_url and DM me the url. Something like:

# Callback for successful connection.
def on_connect(ws, response):
    .....
    print(ws.socket_url)

vijoeyz

Can you re-generate the access token and check again

Does it mean generate using renew_access_token() ?

This is what generate_session() returned:

XXXX

SRIJAN

No,Rakesh sir means to log in again like you do every day and generate a new access token.

rakeshr

Please don't post account-related information here. You can DM me such details.

Does it mean generate using renew_access_token() ?

No, i mean to re-run login flow and generate access token again. For your flask app, you can visit /login.

@app.route("/login")
def login():
.....

vijoeyz

@rakeshr , Thanks for deleting my private data.

I may have logged in about 20 times today, but that doesn't help.

@rakeshr , I have just IM'ed an order executed by the app. All APIs work, it is just that the WS connection fails every time, and therefore, ticks don't arrived.

rakeshr

You were sending an extra quote in your API key for the WebSocket connection. You were sending : ..?api_key='your_api_key'
correct would be : ..?api_key=your_api_key
Hence it kept throwing 403.
