pyspeedtest cannot find test server

This tutorial is I’m trying to use pyspeedtest to get the upload/download speed of my connecting. but I get the error : Exception: Cannot find a test server. If you change the URL in the pyspeedtest.py file from www.speedtest.net to c.speedtest.net on line 186.

sudo vi /usr/local/lib/python3.6/dist-packages/pyspeedtest.py

# Old code
connection = self.connect('www.speedtest.net')

# New code
connection = self.connect('c.speedtest.net')

Now run pyspeedtest using python in /usr/local/lib/python3.6/dist-packages/pyspeedtest.py.

python3 /usr/local/lib/python3.6/dist-packages/pyspeedtest.py

Output:
Using server: speedahm1.jioconnect.com:8080
Ping: 61 ms
Download speed: 30.15 Mbps
Upload speed: 16.44 Mbps

Use Python Interpreter:

>>> import pyspeedtest
>>> st = pyspeedtest.SpeedTest()
>>> st.ping()
245.42123079299927
>>> st.download()
16356456.45678923
>>> st.upload()
17446457.45687456

You getting this error : Exception: Unable to connect to None.

SpeedTest Object takes a host parameter. You need to change pyspeedtest package at all.

# Old code
st = pyspeedtest.SpeedTest()

# New code
st = pyspeedtest.SpeedTest(host="c.speedtest.net")
