I'm getting: "Python handling socket.error: [Errno 104] Connection reset by peer" when I'm trying to run a python script

Question

I'm using Python 2.7 and trying to run the sample python code from this website

########### Python 2.7 #############
import httplib, urllib, base64

headers = {
    # Request headers
    'Content-Type': 'application/json',
    'Ocp-Apim-Subscription-Key': '{subscription key}',
}

params = urllib.urlencode({
    # Request parameters
    'maxCandidates': '1',
})

try:
    conn = httplib.HTTPSConnection('api.projectoxford.ai')
    conn.request("POST", "/vision/v1.0/describe?%s" % params, "{body}", headers)
    response = conn.getresponse()
    data = response.read()
    print(data)
    conn.close()
except Exception as e:
    print("[Errno {0}] {1}".format(e.errno, e.strerror))

    response = conn.getresponse()
    data = response.read()
    print(data)
    conn.close()

I'm getting the following error:

Python handling socket.error: [Errno 104] Connection reset by peer

What should be the problem?
