Python to Qlik sense server connection refused after some requests through websocket.

[Anonymous]

I'm currently working on python to Qlik server connection using JWT authentication method. It works fine for some 3 or 4 requests and then it shows error. I don't know what is wrong with it.

Also, I heard that try to use certificate authentication. but I don't know how to use it with WebSocket. (please provide demo code if possible)

please note that I cannot use a cookie to hold the session with Qlik server because my application is itself Django server and it cannot store a cookie.

below is my python code for authentication.

def __init__(self, senseHost, proxyPrefix, userDirectory, userId, privateKeyPath, ignoreCertErrors=False):
    self.url = "wss://" + senseHost + "/" + proxyPrefix + "/app/"
    privateKey = open(privateKeyPath).read()
    sslOpts = {}
    if ignoreCertErrors:
          sslOpts = {"cert_reqs": ssl.CERT_NONE}
    token = jwt.encode({'UserID': userId, 'UserDirectory': userDirectory}, privateKey, algorithm='RS256')
    self.ws = create_connection(self.url, sslopt=sslOpts, header=['Authorization: BEARER ' + token.decode('utf-8')])
    self.session = self.ws.recv()

Any help!

Thanks,
