The badge you're referencing is hosted by a cloudflare CDN, which uses
"magic" to return error responses to non-humans.

You can see this behavior by running curl against the URL:

curl -I https://anaconda.org/conda-forge/r-tiledb
HTTP/2 400
server: cloudflare
...

I have seen this behavior for other resources, but generally have
experienced 403 responses.

This urlchecker issue discusses what I had seen:
https://github.com/r-lib/urlchecker/issues/26

I do not have guidance other than to either remove the URL or add a note
stating that the 400 errors are only presented to robots. Perhaps CRAN
occasionally adjusts its User-Agent to avoid some of these challenges? Not
sure.

This (status 400) underlies manual inspection and we let this pass.

Best,
Uwe Ligges
