Hey guys,

Hoping someone can explain the issue I'm having with Geolocator...it was working fine yesterday, but now when I run the cell it is coming back with Gateway 502 error. Attached below is the code and error message.

address = 'Chicago, IL, USA'

geolocator = Nominatim(user_agent="class-app")
location = geolocator.geocode(address)
latitude = location.latitude
longitude = location.longitude
print('The geographical coordinate of Chicago are {}, {}.'.format(latitude, longitude))

Error:
AdapterHTTPError                          Traceback (most recent call last)

    361             else:

    374         try:

    405                 )

The above exception was the direct cause of the following exception:

Please advise what I am doing wrong.

Thank you.

probably some temporary problem with Nominatim
right now, if you try the examples here:
https://nominatim.org/release-docs/develop/api/Search/

the xml link return 502 Bad Gateway
https://nominatim.openstreetmap.org/sear...sdetails=1


while the JSON link example works
https://nominatim.openstreetmap.org/sear...ygon_svg=1

OK, now it works, incl. your code
