How do I resolve the "Unable to register" error in WorkSpaces?

Resolution

Check the RegisterWorkspaceDirectory API event in your AWS CloudTrail logs to get the details of the error.

Then, check the following configurations:

• The user that's registering the directory must have workspaces:RegisterWorkspaceDirectory AWS Identity and Access Management (IAM) permissions. To allow the IAM role to run the RegisterWorkspaceDirectory API, you can give the role permissions from the AmazonWorkSpacesAdmin AWS managed policy.
• The directory is unshared. In WorkSpaces, you can use only unshared directories. You can't register a shared directory.
• The subnets that you selected in the registration are mapped to Availability Zones that WorkSpaces supports in your AWS Region.
