[image] Lilly: are these the guides you followed Yes, the first one is what I followed [image] Lilly: are you certain your upload bucket is named “discourse”? Correct [image] I’ll try removing the slashes and will follow up

I removed the trailing slashes, still no luck. Same Unauthorized error. Token is configured properly too [image]

are you certain the cloudflare R2 token has read/write permission and did you correctly configure the CORS policy? i know you have a bit of a unique server configuration, and the cloudflare bucket permissions and configuration need to be exactly correct or it will throw permissions errors.

yea the cloudflare dashboard can be a hornet’s nest of configuration lol. glad you got it fixed!
