Need help to retrieve traffic meter details for WNDR3700v3

[srinivasgnv]

I have enabled traffic metering in the webUI

Following is the code that I am using based on the sample provided

from pynetgear import Netgear
netgear = Netgear(password="xx")
print("Traffic meter details -->>")
traffic = netgear.get_traffic_meter()
print(traffic)

I am using Python 3.7.4
Following is the output I get

$ python3 net.py
Traffic meter details -->>
Invalid response
Invalid response
None

The same code when executed in Python3 version Python 3.7.3
I get the following output

$ python3 traffic.py 
Traffic meter details -->>
Error finding node in XML response
None

Looks like I am missing something. Can you please help?
