Do you know what the correct settings should be for it to work? I tried several options but none of them work, there are many possible combinations

Storage. Default storage engine (other than Local may require custom/additional setup)

Value available: what is the solution supported by UNA? No matter which of these settings I selected, all photos are upload locally.

• S3
• S3v4
• S3v4alt

AWS access key already setup

AWS secret key already setup

AWS bucket : our buchet id already setup

AWS custom domain (require custom DNS setup)

Endpoint (specify if other than Amazon, such as storage.googleapis.com, s3.wasabisys.com)

• s3.us-east-005.backblazeb2.com

Signature version (only S3v4alt storage supports both v2 and v4)

• v4

 Region (for signature v4 only)

• s3.us-east-005

Authenticate using Amazon IAM Role (S3v4alt storage only)

• this setting is required ? I selected them but nothing happens, all the photos are uploaded to the local server

Enable ACLs (S3v4alt storage only)

• this setting is required ? I selected them but nothing happens, all the photos are uploaded to the local server

Force authenticated URLs for specific storages
