unable to generate new acesstoken(POST /session/token HTTP/1.1" 200 None),generating same acesstoken

i am using websocket to fetch real time data ... all was working fine till last friday but from today morning i have been unable to connect to websocket . It is showing 403 forbidden (initialy showed ' closed reason without close code' )for the same code(s) that used to work fine till friday .Tried using the sample code in py documentation but got the same error .

ERROR:kiteconnect.ticker:Connection error: 1006 - connection was closed uncleanly (I dropped the WebSocket TCP connection: close reason without close code)
ERROR:kiteconnect.ticker:Connection closed: 1006 - connection was closed uncleanly (WebSocket connection upgrade failed (403 - Forbidden))
(above errors while getting tickdata)

Thought maybe access token has expired ...
Tried to generate new accestoken(manualy) ,but got the SAME ACCESS_TOKEN everytime for diffferent request_tokens (also tried logging out of kite but for no use). Have been using kite api for some time now, this has happend for the first time . I used kite (android )in the morning before loggingin in kiteconnect , is that where the issues started ?
Have checked and rechecked the details(api key,api secret key , request token(s) ) and code (both for acesss_token and websocket ) multiple times .

Similiar problem was posted in the above discussion but no sol was given there ...

DEBUG:urllib3.connectionpool:https://api.kite.trade:443 "POST /session/token HTTP/1.1" 200 None

would really appreiciate if someone can help a not-so-techie in solving this problem

    failed (403 - Forbidden))
    This error can only come if you are using an wrong access_token in WebSocket initialization. You need to re-check, if you are sending it as a proper string, without padding any extra string/spaces.
  • asto
    thanx for the reply @rakeshr
    checked it again but it is giving the same error and also
    why am i generating the same access token every time ( with different request token) . Is it because I logged in kite (android app) before , i saw in some threads @sujith was saying all kite platforms are interwined due to regulations and logging in (or out) from other platforms can mess with kiteconnect

    iam getting this debug along with same acesstoken
    DEBUG:urllib3.connectionpool:Starting new HTTPS connection (1): api.kite.trade:443
    DEBUG:urllib3.connectionpool:https://api.kite.trade:443 "POST /session/token HTTP/1.1" 200 None

    i had similiiar issues with websocket (403) error weeks ago also , but got sorted out with generating a new accesstoken
  • asto
    @rakeshr in the first message i mentioned a thread with a similiar problem ... but no solution was given in the end
    plz go through the thread( and my initial messsg i hv explained my problem in detail )

    this is the code i use , padding of the string ishighly unlikely bt stll hv stried doing it manualy in various websocket codes (also the sample documentation code with same eror)
    def update_token():
    kite = KiteConnect(api_key="hiding from public")
    x=input('request token here)
    data = kite.generate_session(x, api_secret="hiding from public")
    d = {'api_key': 'removed from public', 'api_secret': 'removed from public' , 'access_token': accesstoken}
    with open('/media/astolisher/data/api/instruments file etc/kite api.txt','w') as file:

    def get_acesstoken():
    f=open('/media/astolisher/data/api/instruments file etc/kite api.txt','r+')
    return acesstoken
    # at=get_acesstoken() in websocket codes
    i highy doubt there is a coding error , its probabaly api functioning error (probably on my end ) or unwareness of dos and donts by a rookie :) :)

    Would really apprecite if you can pinpoint the reason for error and sol for it asap
    and once again thanx for your quick reply
  • asto
    lil update , now errors are iterating between (403,closed reason without close code and dropped tcp without previous closing handshake)

    this is the code i used with asimiliar one for full data ..was working like butter till friday
    accesstoken= 'rNmoo8jcMBR20pxUQ2o3IgTzDIm0CBT7' # write acesstoken

    tokens=functions.activaten100t() #list of stocks to get
    kws = KiteTicker(apikey, accesstoken)
    def on_connect(ws, response):
    ws.set_mode(ws.MODE_LTP, tokens) #cahnge mode
    def on_close(ws, code, reason):
    logging.info('Websocket connection has been closed')
    kws.on_connect = on_connect
    kws.on_close = on_close
    while True :
    def on_ticks(ws, ticks):
    def function1(ticks):
    for t in ticks:
    folder='/media/astolisher/data/live data/' # define the folder to store the into
    ts= symbol_fortoken(i)
    file=initiate_file(tokens=ts,filecolumnslist=['tradingsymbol','instrument_token','last_price','timestamp'],path=folder) # define the columns of the using folder
    dt=pd.DataFrame({'tradingsymbol':ts ,'instrument_token':i,'last_price':l,'timestamp':[time] })
    file.to_csv('/media/astolisher/data/live data/'+ts+'.csv')

    kws.on_ticks = on_ticks

    would appreciate if someone can give it a quick look and help me out
    @sujith @rakeshr
    (i stole this code idea from @rakeshr in some thread ;) so full credits (and thanks ) to him for a simple yet efficient code (till today morning it was :)

    @ sujith @rakeshr can someone please help me out here
    iam stuck frrom past two days ...
  • sujith
    Can't figure out anything here. It seems fine. Maybe print and see if you are sending valid api_key and access_token.

    I am also facing the same issue as @asto is going through. It was working till yesterday and today i have logged into the kite web application before generating REQUEST_TOKEN and ACCESS_TOKEN. Websocket connection is closing with the same issue as mentioned above by @asto 'Connection closed: 1006 - connection was closed uncleanly (peer dropped the TCP connection without previous WebSocket closing handshake)'.

    I have tried generating the both REQUEST_TOKEN and ACCESS_TOKEN multiple times and observed that the ACCESS_TOKEN remained same even when NEW REQUEST_TOKEN is generated.

    Have also tried deleting the session token using the call 'DELETE /session/token Logout and invalidate the API session and access_token' call mentioned in 'https://kite.trade/docs/connect/v3/user/' page which was successful.

    This time around after deleting the session token, i could generate the NEW REQUEST_TOKEN and NEW ACCESS_TOKEN but still observed that the websocket started failing with the same issue.

    I have been using Kite Connect streaming for a quite long time now and it was working fine till yesterday i.e September 19. Today i feel the logging into the application before generating the tokens have something to do with the issues i am observing. I never faced any issue like this before even when i logged into the application before generating the tokens.

    Was there any new changes that has been pushed recently or was there any version changes for any of the packages that the platform is using which is breaking the current functionality or is there something else which is effecting the functionality which was working perfectly for last few months.

    @sujith @rakeshr @MAG Kindly have a look into the same and let us know the solution with. Would appreciate your time in this regard.

    Just a update: Checked out most of the possibilities and have also checked that there are no spaces or tabs being introduced for REQUEST_TOKEN and ACCESS_TOKEN tokens.

    And also even tried logging out from all the kite applications, deleted tokens with the request mentioned above and generated new REQUEST_TOKEN and ACCESS_TOKEN tokens and tried too. Seems the issue exists.

    Environment: Using Python API to authenticate and access kite connect.

    Thanks & Regards

    @sujith workin fine now ,it seems it was an exceptional erorr on api part (which probably blocked access to websocket and api.generete_session for some reason )
    got sorted out after i generated a new token in the afternoon and sorted out a few rather surprising errors in my codes ( tokens have to defined manully in a list, it isnt working if called by a function and that is still the case @sujith functions have been checked and rechecked many times, the list is same as the one being sent manualy yet its showing 1006 closed uncleanly.. :/ )

    * try getting a token tomo when tokens get refreshed and do it bedore logging into any other kite instrument ( i logged in kite android yesterday probably that was were the problems started )
    *look in you codes for erors (like kws.connect put inside a function )

    * try defining tokens manually which worked for me :)
    * most imp run a safe ( documentation ) code in the morning ,
    *try changeing Ides

    *give it a few tries with different environments ... mine took a dozen attempts( along with couple of changes mentioned above in my code) to start functioning smoothly again

    @pdommata try the things above , if you still face the issues feel free to send your code i ( and far more experienced devs than me) would surely look into code :)

    @sujith @rakeshr a humble req to plz look into such unique errors on api's end , kite api is such a usefull tool with such a good broker but such unwanted errors (with no sols found in whole forum) totally spoils the fun (and makes you feel helpless)
    and also pin this discussion atleast one will get to know that this type of error is posssible and not just god saying f*** u trader

    Hello @asto,

    I generally do generate tokens manually. (Correct me if i am wrong if i am not doing so with the below code pasted below.)

    Code to generate tokens:
    ---------------------------- authenticate_app.py----------start----------------------
    from kiteconnect import KiteConnect
    from kiteconnect import KiteTicker
    import pandas as pd
    import datetime
    import pdb
    import json, config
    import numpy as np
    import pandas as pd
    import json
    import asyncio

    kws = ""
    kite = ""

    api_key = config.API_KEY
    api_secret = config.API_SECRET
    request_token = config.REQUEST_TOKEN
    access_token = config.ACCESS_TOKEN

    def get_login(api_key, api_secret):
    global kws, kite
    kite = KiteConnect(api_key=api_key)
    print("[*] Generate access Token : ", kite.login_url())
    request_token = input("[*] Enter Your Request Token Here : ")
    data = kite.generate_session(request_token, api_secret=api_secret)

    get_login(api_key, api_secret)


    Code to use the generated tokens to initiate the stream below:
    from kiteconnect import KiteConnect
    from kiteconnect import KiteTicker
    import pandas as pd
    import datetime
    import pdb
    import json, config
    import numpy as np
    import pandas as pd
    import json
    import asyncio

    kws = ""
    kite = ""

    api_key = config.API_KEY
    api_secret = config.API_SECRET
    request_token = config.REQUEST_TOKEN
    access_token = config.ACCESS_TOKEN

    tokens = [61307911]

    def get_login(api_key, api_secret):
    global kws, kite
    kite = KiteConnect(api_key=api_key)
    kws = KiteTicker(api_key, access_token)

    def on_ticks(ws, ticks):
    for tick in ticks:

    def on_close(ws):
    print("Connection closed")

    def on_connect(ws, response):
    ws.set_mode(ws.MODE_FULL, tokens) # MODE_FULL , MODE_LTP, MODE_QUOTE

    # get_login(api_key, api_secret)
    # kws.on_ticks = on_ticks
    # kws.on_connect = on_connect
    # kws.connect()

    kite = KiteConnect(api_key='')
    kws = KiteTicker('', '')
    kws.on_ticks = on_ticks
    kws.on_connect = on_connect


    Please correct me if i am doing something wrong here. If you observe in initiate_stream.py -- i have commented out code (bolded) which i have been using to use the details that are maintained in config file. But today i have directly given the tokens as in the code (Italic) and tried as well. This also is failing.

    Usually i generate tokens and then i push my code to run on Google cloud servers.

    Your time would be appreciated.

    Thanks and Regards

    Hello @asto and Everyone,

    Update here. Sorry my bad. I have subscribed to only one instrument_token which has expired and it seems to be the issue due to which my websocket has been getting disconnected.

    Thanks again.
