Images from BackBlaze by b2 CNAME not working more in the staging enviroment
Hi there - I’m Pat Patterson, Chief Technical Evangelist at Backblaze. I might be able to help figure this out…
Hi,
Yes, it was working before. We haven’t changed anything about Blackbaze or Cloudflare. All buckets are public. We are only using the b2 CNAME for “f005.backblazeb2.com”. See this example:
The image loads normally, but in our app, it doesn’t:
https://cognittron-staging .fly.dev/learn
It used to load, but since we don’t have any domain configured for staging, we use this fly subdomain, but it doesn’t work. We have another instance “plataforma.superfoco.com.br”, where I had to change all the images to make it work. to something like this “b2.superfoco.com.br/file/superfoco-public/images/T02-thumb.webp”. But this is not the temporary solution I found it does not break in production, but not loading these images complicates the test locally, and also have other project members test things on staging. I believe it is a Cors issue or something like that, but in Blackblaze everything is configured correctly with “Share everything in this bucket with all origins”.
I don’t know how to edit my reply, so:
The correct is:
“But this is the temporary solution I found it does not break in production”
And the example image:
Another example is our website: UniCTE
Some images do not load because are with the link b2.unicte.com:
But this is the staging of Cloudflare, it does not make sense not wok.
I can retrieve https://b2.unicte.com/file/unicte-public/trail_icons/pontos-criticos_armadilhas-sistemas-prediais_rectangle_1703620899626.jpeg via curl at the command-line just fine:

But when I try to open it in the browser (in a new tab), I get this error:

Turn off Hotlink Protection, and it should work.
Thanks, It’s right, I turn off the hotlink protection and the images are loading again.
