I'm getting a

<urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:852)>

When I try to validate captchas in my django project. This is how i do it:

  recaptcha_response = request.POST.get('g-recaptcha-response')
  print(recaptcha_response)
  url = 'https://www.google.com/recaptcha/api/siteverify'
  values = {
      'secret': settings.CAPTCHA_SECRET_KEY,
      'response': recaptcha_response
  }
  data = urllib.parse.urlencode(values).encode()
  req =  urllib.request.Request(url, data=data)
  response = urllib.request.urlopen(req) # It fails here
  result = json.loads(response.read().decode())
  print(result)

The site has a valid certificate, and it works on local. In the log i'm getting this:

Request Method: POST

Request URL: http://prod.xxxx.com/evalua

Which is weird because the site works in https. Its on kubernetes, could that be the problem? I really have no idea what the problem IS? I have the captcha keys correctly set up in de recaptcha admin console. And the certificate are not autosign. I use lets encrypt
