@cadusilva I've figured it out. Previously I was routing my images through the S3 front end, e.g., `s3.eu-central-000.backblazeb2.com`, but it looks like Backblaze made a change to the hostname so that it is `<BUCKET NAME>s3.eu-central-000.backblazeb2.com`. I've changed my CDN to use the friendly hostname `f000.backblazeb2.com` and everything seems to work fine now.
