Sounds like a misconfiguration (HTTPS on an HTTP port or some other non-HTTPS protocol).
I’ve seen this before in only one instance, which is when archive.is started blocking Cloudflare’s DNS (because they use DNS to hack together a CDN and Cloudflare doesn’t send the optional data they need), but that would make it intentional. If catbox is sabotaging DNS providers the same way, maybe try another upstream DNS server.

I changed my DNS to quad9 and that fixed it. Wild.
Must be the same type of misconfiguration/sabotage, then. How annoying.
