linkinator and curl disagree on link status

[chalin]

linkinator reports a status of 0 for https://developer.android.com/reference/android/os/Build as shown here:

$ npx linkinator https://developer.android.com/reference/android/os/Build --verbosity DEBUG

      },
      "responseType": "stream",
      "timeout": null
    }
  },
  null
]
ERROR: Detected 1 broken links. Scanned 1 links in 3.258 seconds.

But if I use, say, curl or visit the link manually and look at the network traffic, all I see are 200 status codes. For example:

$ curl -o - -I https://developer.android.com/reference/android/os/Build 
HTTP/2 200 
last-modified: Thu, 10 Feb 2022 17:54:54 GMT
content-type: text/html; charset=utf-8
...

Why the difference?

I'm seeing something similar with a microsoft.com link, and a few other sites

Ditto on this. I'm trying to run linkinator against a localdev site which i can curl without issue, but linkinator gives me a 0 error code.
