Response headers Etag unverified


I’m testing my website in development through with Zero Trust access.

I do have some images on a Backblaze B2 bucket, and I’m following this procedure with Cloudflare Transform Rules: Free Image Hosting With Cloudflare Transform Rules and Backblaze B2

Everything works as expected, except that I get “ETag: unverified: …” (why “unveririfed”?) and “Cache-Control: max-age=31536000” instead of “Cache-Control: public, max-age=31536000” (missing “public”).

Why is that?

Here’s the response headers:

The unverified part of the ETag is from B2, ask them about it. It’s referenced in Uploading
