401 unauthorized when uploading to r2 presigned url
I was using the presigned url to upload image to my r2, a few month ago it works, I didn't change anything and it broke now, I get this error. My CORS configuration should be correct. I tried to post to the url using postman, and it said 401 unauthorized, not sure if that's because of my custom domain? could anyone help me please, thanks in advance!
