Thanks for the screenshot. Yes, that’s it. And it’s the same for https. I have automatic redirects to https, i.e. the site is only accessible via https with SSL.
I’ve seen the DNSSEC error. If that is the problem, I will fix it. But I am not sure if that is the problem. Because DNSSEC was never enabled at all, and the blacklist happened today, not even a week ago.
So why today? If getting clarification on what exactly to fix, I would fix it.
