aws smb for windows not connecting to active directory made by AWS director

I am trying to set up a network drive on my windows 10 home desktop that can reach my files in S3 using the storage gateway. I have done the following:

1.) Set up a m4.xlarge EC2 server with 150GB of EBS to serve as cache
2.) I have configured the required ports of 80, 22, 139, and 445 for SMB
3.) I have used AWS active directory service to set up my microsoft AD in the AWS cloud
4.) I have created the file gateway
5.) When I click edit SMB settings and type in my active directory, username, and password, the active directory status says failed to join ( network error).

Can someone please help me? I have had no luck and have been going around in circles.
