I have an URL, I call it https://testsite.test.de/Interfaces, looks like the real one. When I enter the URL into the Browser it immediately opens a Username and Password window.

When I click Inspect in Firefox the inspector is empty, only under network there is one line with GET and the URL. Under security it shows: Protocol version: "TLSv1.2"

After logging in, there should appear “Connected to websocket” and there is a real time data stream shown which I want to scrape into to further analyze.

What I did:

import requests

username = 'myname'
password = 'mypassword'
headers = {'User-Agent' : 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:125.0) Gecko/20100101 Firefox/125.0'}
login_data = {
    'Benutzername': username,
    'Passwort': password
    }

r = requests.get('https://testsite.test.de/Interfaces', 
                 headers=headers, 
                data=login_data)
print(r.status_code)

The output is status code: 401

This is what “Inspect” in Firefox shows:
