Почему мой python запрос к http выполняется, а не к https?

Мне нужно подключиться к этому uri: uri = 'https://www.wfs.nrw.de/geobasis/wfs_nw_inspire-flurstuecke_alkis?SERVICE=WFS&VERSION=2.0.0&REQUEST=GetFeature&STOREDQUERY_ID=urn: og c: def: запрос: OG C -WFS :: GetFeatureById & ID = CadastralParcel_05518904700963 ______ '

Поскольку это не работает, я попробовал это, чтобы найти мои ошибки: 

import requests
import urllib.request

uri = 'http://www.google.de'
uriS = 'https://www.google.de'

myproxies =  urllib.request.getproxies()

try:
    r = requests.get(uri)
    print('HTTP OK')
except:
    print('HTTP NOT OK')
try:
    r = requests.get(uri, proxies = myproxies)
    print('HTTP WITH PROXIES OK')
except:
    print('HTTP WITH PROXIES NOT OK')
try:
    r = requests.get(uriS)
    print('HTTPS OK')
except:
    print('HTTPS NOT OK')
try:
    r = requests.get(uriS, proxies = myproxies)
    print('HTTPS WITH PROXIES OK')
except:
    print('HTTPS WITH PROXIES NOT OK')

Это результат: 

HTTP OK
HTTP WITH PROXIES OK
HTTPS NOT OK
HTTPS WITH PROXIES NOT OK

Это происходит, когда я делаю это в консоли : 

>>> import requests
>>> uri = 'https://www.google.de'
>>> r = requests.get(uri)

Мы решили проблему!

Код был верным.

Мы (наш сетевой администратор) поставили uri "https://www.wfs.nrw.de" на список для URI без аутентификации не требуется. 

import requests
import urllib.request
myproxies = urllib.request.getproxies()
uri = 'https://www.wfs.nrw.de/geobasis/wfs_nw_inspire-flurstuecke_alkis?SERVICE=WFS&VERSION=2.0.0&REQUEST=GetFeature&STOREDQUERY_ID=urn:ogc:def:query:OGC-WFS::GetFeatureById&ID=CadastralParcel_05518904700963______'
r = requests.get(uri, proxies = myproxies)
print(r.text)
...
