Why does my python request to http runs, but not to https?

Question

I need to get a connection to this uri: 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______'

Because it dosen't work, i tryed this to find my misstakes:

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')

This is the result:

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

This happens when i do it in the console:

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

• Dave Costa: You should print out some details from the exceptions.
• Alexandre Senges: It's hard to answer like that. It could be different reasons. You shouldn't catch the error to see what the stack trace is. My intuition would be that you have a problem with you OpenSSL installation.
• Craicerjack: Does this answer your question? Python requests API using proxy for https request get 407 Proxy Authentication Required
• Wulf: The information was intressting, but we solved the Problem in an other way.

Answer 1

We solved the Problem!

The code was correct.

We (oure network admin) have put the uri "https://www.wfs.nrw.de" on a list for uri with no authentication needed.

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)
