I can't upload photo after setting Cloudflare R2

hi, my CORS policy is same as yours. After setting S3 region to N. Virginia, it works! Thanks for your advice!

I tried some regions except Virginia, all failed. Only Virginia works. This is a tricky point, as I found other document didn’t highlight this, they said “choose a nearest region is OK”. But experiment proves only Virginia is the right choice!

Thanks!
