splunklib.binding.AuthenticationError: Autologin succeeded, but there was an auth error on next request. Something is very wrong

I am connecting to Splunk using splunklib and connecting to splunk in the following manner using Username and password:-

service = client.connect(host=host_name,
                             scheme="https",
                             port=splunk_conf["port"],
                             username,
                             password,
                             autologin=True,
                             verify=False)

Even though autologin is set to true I am getting the below error

splunklib.binding.AuthenticationError: Autologin succeeded, but there was an auth error on next request. Something is very wrong

I tried adding basic = true as suggested in the link https://github.com/splunk/splunk-sdk-python/issues/219 but that is making the queries slow as it requires to login for every splunk query.
