Network connection issue, to ec2 and FTP inside of VPC

Hello I created this instance https://us-east-1.console.aws.amazon.com/ec2/home?region=us-east-1#InstanceDetails:instanceId=i-0ca9edd25728c4f62

The goal is trying to create AD user from that instance, therefore both the AD and EC2 are under the same VPC.

Question 1: I couldn't connect to the EC2 instance with RDP. I configured both the subnet and EC2 to accept RPC calls with ACL, no effect.

Question 2: eventually, I'd like to use this https://us-east-1.console.aws.amazon.com/transfer/home?region=us-east-1#/servers/s-d0e008162fc04aa1a to recieve FTP file drops from the AD's user.

Is the network correctly configured?

Thank you!
