AWS S3 上传 - 无法在未设置凭据的情况下签名请求

Tried now, to set up IAM User with credentials and give it s3:* permissions, and now the upload works, but discourse can´t display it afterwards:

As I´m working in a company, and there are SCP (Service control policies) active for our accounts, it seems that public access is generally blocked

Seems to be no S3 for me (and everyone having the same restrictions for his accounts)

Giving up now … :frowning:
