Description of the bug

When I execute the script browser opens up file temp location and after some time I'm getting error message:
Unable to connect with the browser
Had to do
BROWSER_PATH = '/usr/bin/firefox'
before because it couldn't find it.

Running openSUSE Tumbleweed. Necessary python packages are installed from the repo.

Steps to reproduce the behavior

1. Install python311-pycryptodomex python311-websocket-client via package manager
2. execute 'python3 NFAuthenticationKey.py'
3. temp location is opened in browser
4. -> error message after some time
