Try the following to resolve issues related to connecting to your instance:

Verify that you're using the correct public DNS hostname. (In the Amazon EC2 console, select the instance and check Public DNS (IPv4) in the details pane.) If your instance is in a VPC and you do not see a public DNS name, you must enable DNS hostnames. For more information, see DNS attributes for your VPC in the Amazon VPC User Guide.

Verify that your instance has a public IPv4 address. If not, you can associate an Elastic IP address with your instance. For more information, see Elastic IP addresses.

To connect to your instance using an IPv6 address, check that your local computer has an IPv6 address and is configured to use IPv6. If you launched an instance from a Windows Server 2008 SP2 AMI or earlier, your instance is not automatically configured to recognize an IPv6 address assigned to the instance. For more information, see Configure IPv6 on your instances in the Amazon VPC User Guide.

Verify that your security group has a rule that allows RDP access. For more information, see Create a security group.

If you copied the password but get the error Your credentials did not work, try typing them manually when prompted. It's possible that you missed a character or got an extra white space character when you copied the password.

Verify that the instance has passed status checks. For more information, see Status checks for your instances and Troubleshoot instances with failed status checks (Amazon EC2 User Guide for Linux Instances).

Verify that the route table for the subnet has a route that sends all traffic destined outside the VPC to the internet gateway for the VPC. For more information, see Creating a custom route table (Internet Gateways) in the Amazon VPC User Guide.

Verify that Windows Firewall, or other firewall software, is not blocking RDP traffic to the instance. We recommend that you disable Windows Firewall and control access to your instance using security group rules. You can use AWSSupport-TroubleshootRDP to disable the Windows Firewall profiles using SSM Agent . To disable Windows Firewall on a Windows instance that is not configured for AWS Systems Manager, use AWSSupport-ExecuteEC2Rescue, or use the following manual steps:
