+ + tl;dr - You’re going to want to use a Hetzner-external resolver (1.1.1.1/8.8.8.8/9.9.9.9) if you’re going to attempt to resolve your own server’s address(es) from your own server. This is a variation of an issue that has already been discussed some on reddit, but it’s not about Hetzner DNS being down but more about recursive queries not working (and finding this via cert-manager running on a Kubernetes cluser).
