Issues setting up FSx with self managed active directory

Hi, Ran the amazon fsx validation tool and got no errors But when I try to setup the Fsx i get the following error:

File system ID

fs-01117e89344a09962 Failure message

File system creation failed. Amazon FSx is unable to communicate with your Microsoft Active Directory domain controllers. This is because Amazon FSx can't reach the DNS servers provided or domain controllers for your domain. To fix this problem, delete your file system and create a new one with valid DNS servers and networking configuration that allows traffic from the file system to the domain controller as recommended in the Amazon FSx user guide: https://docs.aws.amazon.com/fsx/latest/WindowsGuide/self-manage-prereqs.html.

Any suggestions ? Thanks
