failed to import image due to DNS resolution failure, but the host appears in DNS

[davepacheco]

Working around #4595 I tried to import an image using a URL like this:

dap@ivanova ~ $ echo '{"name": "my-image", "description": "dummy", "os": "debian", "version": "11", "source": { "type": "url", "url": "http://catacomb.eng.oxide.computer/media/cloud/debian-11-genericcloud-amd64.raw", "block_size": 512 } }' | oxide image create --name my-image --description my-description --os debian --version 11 --json-body /dev/stdin
error
Error Response: status: 400 Bad Request; headers: {"content-type": "application/json", "x-request-id": "208426d0-dafd-40ad-94be-2e5566bb2737", "content-length": "380", "date": "Fri, 01 Dec 2023 17:21:52 GMT"}; value: Error { error_code: Some("InvalidValue"), message: "unsupported value for \"url\": error querying url: error sending request for url (http://catacomb.eng.oxide.computer/media/cloud/debian-11-genericcloud-amd64.raw): error trying to connect: dns error: failed to lookup address information: node name or service name not known", request_id: "208426d0-dafd-40ad-94be-2e5566bb2737" }

I assume it's saying that Nexus (or maybe some part of Crucible?) failed to resolve catacomb.eng.oxide.computer in DNS. But it's in the public DNS:

$ dig catacomb.eng.oxide.computer @1.1.1.1 

; <<>> DiG 9.18.19 <<>> catacomb.eng.oxide.computer @1.1.1.1

I'm wondering if whoever's doing this DNS resolution isn't using the right DNS servers? (But then how does this ever work?)

In case it matters, this system (madrid) was configured with these DNS servers (as in, these were in the rack setup config file I gave to wicket):

dns_servers = [
    "1.1.1.1",
    "9.9.9.9",
]
