Streaming video on GAE

Why am I getting this error? and this is what I call the streaming API.

import tweepy
import sys

creds = json.loads(open('credential.json').read())
tw_consumer_key = creds['tw_consumer_key']
tw_consumer_secret = creds['tw_consumer_secret']
tw_access_token = creds['tw_access_token']
tw_access_token_secret = creds['tw_access_token_secret']

try:
    auth = tweepy.OAuthHandler(tw_consumer_key, tw_consumer_secret)
    auth.set_access_token(tw_access_token, tw_access_token_secret)
    api = tweepy.API(auth)
except Exception:
    service = None
    api = None    

# Query terms
Q = "Better"

class CustomStreamListener(tweepy.StreamListener):
    def on_status(self, status):
        try:
            print "%s\n%s\n%s\n%s\n\n" % (status.text, 
                                      status.author.screen_name, 
                                      status.created_at, 
                                      status.source,)
        except Exception, e:
            print >> sys.stderr, 'Encountered Exception:', e
            pass

    def on_error(self, status_code):
        print >> sys.stderr, 'Encountered error with status code:', status_code
        return True # Don't kill the stream

    def on_timeout(self):
        print >> sys.stderr, 'Timeout...'
        return True # Don't kill the stream



class LiveStream(webapp2.RequestHandler):
    def get(self):
        streaming_api = tweepy.streaming.Stream(auth, CustomStreamListener(), timeout=60)
        self.response.out.write(streaming_api.filter(track=Q))

Probably the reason for GAE does not allow the socket, I'm not sure how to apply the query term to receive certain filtered stream tweets. My goal with this part of the code is to get the live broadcast with the assigned keywords. If there are alternative methods, please contact.
