I can't upload photo after setting Cloudflare R2

hi @haha welcome

1. you should set the region to US East (N. Virginia):

2. does your CORS policy on cloudflare via json looks like this? you need the ETag exposed header.

[
  {
    "AllowedOrigins": [
      "https://forum.example.com" 
    ],
    "AllowedMethods": [
      "GET",
      "PUT",
      "POST",
      "DELETE",
      "HEAD"
    ],
    "AllowedHeaders": [
      "*"
    ],
    "ExposeHeaders": [
      "ETag"
    ],
    "MaxAgeSeconds": 3000
  }
]
