#### S3 Bucket Region Might Need to Be Set Manually

In Studio Pro version 11.6, the AWS S3 library was updated from version 1 to version 2.

In some scenarios (legacy or custom S3 endpoints), this autodetection might not work correctly. In this case, you can manually specify the S3 bucket region by setting the [com.mendix.storage.s3.Region](/refguide/custom-settings/#commendixstorages3Region) Custom Runtime Setting. A manually specified `com.mendix.storage.s3.Region` will override the autodetected bucket region.

Mendix Operator versions 2.24.2 (and older) does not autodetect S3 bucket regions. To use Mendix 11.6 (or the latest LTS versions), manually set the `com.mendix.storage.s3.Region` custom Runtime setting. You can also consider upgrading to Mendix Operator 2.25.0 or newer.
