In [this issue](https://mattermost.atlassian.net/browse/PLT-7475), it says that the UI text should be `Help Text: (Optional) AWS region you selected when creating your S3 bucket. If no region is set, Mattermost attempts to get the appropriate region from AWS, or sets it to "us-east-1" if none found.`
The [Mattermost documentation](https://docs.mattermost.com/administration/config-settings.html#amazon-s3-region) says the default for this value is `""`, but it's set here. For this reason the behavior described above (getting the appropriate region from AWS, then falling back to `us-east-1` only if that fails) **does not happen**; Mattermost tries region `us-east-1` even if `AmazonS3Endpoint` points to a different region.
