Consider the following rules and guidelines when you configure the region name of the bucket in the connection properties.
•When you change the runtime environment of an existing connection, the region is changed to the default region US East (N. Virginia). Select the region manually to change the default region.
•When you edit an existing connection, you see duplicate entries for regions. Use the regions that contain spaces because these regions are populated from AWS SDK. For example, use US West (Oregon) instead of US West(Oregon).
