I really wonder what else could block. Both my Windows machine and my Mac Mini are on the same switch, connected to the same router. My Mac works without any problems, my Windows computer also never had any problems over all the years (and Windows versions). This only started until upgrading to Windows 11. What could still block in safe mode? I have not faced any other issues yet (with all my other programs connecting to various sources).
I have to verify, if my Python program I've written some time ago is still working (it connects to an external REST API). Maybe the internal URLs are somehow blocked - I'm puzzled
