urllib3 warning ReadTimeoutError while connecting to Nominatim's geolocator

Question

The code below code to extract pincodes, but raises the error below. How to work around this?

def get_zipcode(df, geolocator, lat_field, lon_field):
    location = geolocator.reverse(str(df[lat_field]) + "," + str(df[lon_field]))
    # print(location)    #-- uncomment this in case of checking the output
    #return location.raw['address']['postcode']
    
    if location == None:
        return "none"
    else:
        return location.raw['address'].get('postcode')

geolocator = geopy.Nominatim(user_agent="MyGeocodingScript")


zipcode = df.apply(get_zipcode, axis=1, geolocator=geolocator, lat_field='GPS_Lat', lon_field='GPS_Lon')

Error:
