geocoder Service error in python - proxy

Question

I am having a service error as I am trying to run geocoders from geopy to get a location coordinates in python.I have set my proxy config, given it an api_key.
Im not sure why I am getting this error. From the search that I have done on this, it seems that this might be a proxy issue but I have that set up already.
What could be the problem here?
This is my code :
from geopy import geocoders
proxies={'http': 'http://location:port', 'https': 'http://localhost:port'}
api_key = '.......'
g = geocoders.GoogleV3(api_key=api_key,proxies=proxies, timeout=10)
location = 'Mountain View, CA'
try:
place, (lat, lng) = g.geocode(location)
except ValueError as error_message:
print("Error: geocode failed on input %s with message %s" % (location, error_message))
this is my error output:

I modified your code as below, as I don't use proxy and apply an API, and it works in my machine.
from geopy import geocoders
#proxies={'http': 'http://location:port', 'https': 'http://localhost:port'}
#api_key = '.......'
g = geocoders.GoogleV3()
location = 'Mountain View, CA'
try:
place, (lat, lng) = g.geocode(location)
except ValueError as error_message:
print("Error: geocode failed on input %s with message %s" % (location, error_message))
print (place, lat, lng)
Here is the result.
Mountain View, CA, USA 37.3860517 -122.0838511
From the trackback, it looks all the errors are related to SSL. You may try to add below code at the beginning to disable SSL Certification verification as an alternative.
import ssl
# Disable SSL certificate verification
try:
_create_unverified_https_context = ssl._create_unverified_context
except AttributeError:
# Legacy Python that doesn't verify HTTPS certificates by default
pass
else:
# Handle target environment that doesn't support HTTPS verification
ssl._create_default_https_context = _create_unverified_https_context
I have encountered similar problem in Anaconda running Python 2.7 in a env with the root running Python 3.6. The problem wasn't encountered in Anaconda with both root and env running Python 2.7 in another machine.
In addition, this SO post about proxy server set up for geopy using os module may be good reference.
Hope this help.
