Hello, months after the launch, 1.1.1.1 still doesn’t work for me. I’m on the Orange France network (fiber).
I believe it was said that it was because Orange’s engineers used 1.1.1.1 as a local IP in their router, but you said that you were working with them so that they can fix that. It’s seems that nothing has been done on their side since, so it might be time to remind them.
1.0.0.1 works.
