Unable To Fetch Quotes

Unable to fetch quotes at all ... Even after 10 retries.

Traceback (most recent call last):
File "./firecom.py", line 92, in
quote = kite.quote("NFO",tradingsymbol)
File "/usr/local/lib/python2.7/dist-packages/kiteconnect/__init__.py", line 404, in quote
return self._get("market.quote", {"exchange": exchange, "tradingsymbol": tradingsymbol})
File "/usr/local/lib/python2.7/dist-packages/kiteconnect/__init__.py", line 463, in _get
return self._request(route, "GET", params)
File "/usr/local/lib/python2.7/dist-packages/kiteconnect/__init__.py", line 554, in _request
raise(exp(data["message"], code=r.status_code))
kiteconnect.exceptions.DataException: Exception fetching quote
