Reverse gecoding - geopy.Nominatim module throws urlopen error [SSL: UNKNOWN PROTOCOL]

I am trying to get the address details from Latitude and Longitude using geopy.Nominatim module. Am getting "<'urlopen error [SSL: UNKNOWN_PROTOCOL] unknown protocol (_ssl.c:727)>" error.

Version Details :  Python version : 2.7  geopy version : 1.23.0  geographiclib : 1.50  (Dependency with geopy)  requests : 2.25.1  chardet : 3.0.4 (Dependency with requests)  urllib3 : 1.25.10 (Dependency with requests)  idna : 2.10 (Dependency with requests)  certifi : 2020.6.20 (Dependency with requests)  

Code:  =====  from geopy.geocoders.osm import Nominatim  from geopy.exc import GeocoderServiceError       def reverse(lat,long):        app = Nominatim(user_agent='reverse-geocoding')      coordinates = "{},{}".format(lat,long) # not giving the actual co-ordinates      try:          address_details = app.reverse(coordinates,language="en").raw          return address_details      except GeocoderServiceError as e1:          print (str(e1))    result = reverse(lat,long)  print(result)  

================ I have used the following workarounds with the same script.Am getting "<'urlopen error [SSL: UNKNOWN_PROTOCOL] unknown protocol (_ssl.c:727)>" error

workaround 1: To use the CA bundle used by requests library:

from geopy.geocoders.osm import Nominatim  from geopy.geocoders import options  from geopy.exc import GeocoderServiceError  import ssl  import certifi    def reverse(lat,long):      ctx = ssl.create_default_context(cafile=certifi.where())      options.default_ssl_context = ctx      app = Nominatim(user_agent='reverse-geocoding')      coordinates = "{},{}".format(lat,long) # not giving the actual co-ordinates      try:          address_details = app.reverse(coordinates,language="en").raw          return address_details      except GeocoderServiceError as e1:          print (str(e1))    result = reverse(lat,long)  print(result)  

Workaround 2: To disable TLS certificate verification completely:

from geopy.geocoders.osm import Nominatim  from geopy.geocoders import options  from geopy.exc import GeocoderServiceError  import ssl      def reverse(lat,long):      ctx = ssl.create_default_context()      ctx.check_hostname = False      ctx.verify_mode = ssl.CERT_NONE      options.default_ssl_context = ctx      app = Nominatim(user_agent='reverse-geocoding')      coordinates = "{},{}".format(lat,long) # not giving the actual co-ordinates      try:          address_details = app.reverse(coordinates,language="en").raw          return address_details      except GeocoderServiceError as e1:          print (str(e1))    result = reverse(lat,long)  print(result)  

Could anyone please help me to find a fix for this issue.
