Once fixed, you may want to test with explicit content type: HEAD /ipfs/cid?format=raw + pass Accept: application/vnd.ipld.raw to ensure your requested trustless block responses and avoid issues if the other end supports deserialized responses as well.

There is a risk of false positive if deserialized response happens to fit in a single block, so choosing CID of a chunked data may be a good idea.
