+- [Owner](/iam/concepts/#owner) status or [IAM permissions](/iam/concepts/#permission) allowing you to perform actions in the intended Organization
+
+
+## Problem
+
+One of the following messages display when trying to access your bucket using Scaleway Object Storage:
+
+- `Failed to preprocess target Error: S3 error: Access Denied`
+- `Error: Shared memory connection was closed.`
+- `Failed to upload disk 'shadowSpec>'`
+- `Agent failed to process method {DataTransfer.SyncDisk}.`
+
+#### Cause
+
+The application cannot access the Object Storage resource.
+
+#### Solution
+
+If you encounter one or several of the error messages above:
+
+- Check for issues with your API key by following [this procedure](/object-storage/troubleshooting/api-key-does-not-work/).
+
+- make sure that you have the `ObjectStorageFullAccess` [IAM permission](/iam/concepts/#permission).
+
+- make sure that there is no [bucket policy](/object-storage/api-cli/bucket-policy/) preventing the application to access your bucket.
+
+## Going further
+
+- If you did not manage to identify the error and solve it by yourself, [open a support ticket](/account/how-to/open-a-support-ticket/), and provide as many details as possible, along with the necessary information below:
+    - Object Storage Endpoint (e.g. `s3.fr-par.scw.cloud`)
+    - Bucket name
+    - Object name (if the request concerns an object)
+    - Request type (PUT, GET, etc.)
+    - HTTP status code
+    - Date and time (timestamp)
+    - User-agent (SDK, client, console, etc.)
+    - Transaction ID (if possible)
+    - Log / trace of the error (if possible)
