Can't upload pictures, but can upload files

[chuan1127]

I use private deployment, using Minio+postgresql16+casdoor. Now I can successfully upload files, but an error will be reported for image types:
File upload failed.
Please check your network connection and ensure that the file storage service's cross-origin configuration is correct.

But I don’t know where the problem is, and I don’t know how to troubleshoot it. Is there a variable that is not set or something else?
