The authorization header is malformed; the region is wrong; expecting 'ap-southeast-1'. when airbyte connect to s3

The error message "The authorization header is malformed; the region is wrong; expecting 'ap-southeast-1'" indicates that there is a mismatch between the region specified in your S3 connection configuration and the actual region of your S3 bucket. Here are a few steps to troubleshoot and resolve this issue: 1. Verify Region Configuration: Ensure that the region specified in your Airbyte S3 connector configuration matches the region where your S3 bucket is located. For example, if your bucket is in the

ap-southeast-1

region, make sure this is correctly set in the configuration. 2. Custom Endpoint Configuration: If you are using a custom endpoint, ensure that the endpoint URL and the region are correctly specified. There was a similar issue reported where the interface forced users to select a region from a fixed list, which might not match the custom endpoint's region. This could lead to the authorization header being malformed. Reference: [Github Issue #20860](https://github.com/airbytehq/airbyte/issues/20860) 3. Check Access Key and Secret: Double-check that your AWS Access Key ID and Secret Access Key are correctly entered and not flipped. Incorrect credentials can also lead to authorization errors.

There have been reports of DNS issues causing failures in HTTP requests to S3.
