Issue connecting to EC2 windows instance

Question

I'm exploring the EC2 service of AWS.

I'm currently creating a ec2 windows instance. I have launched it in a custom created VPC having a public subnet.

Security group is created and associated with VPC with rules of allow all inbound traffic[0.0.0.0/0](for testing purpose only).

However after getting the admin password (received after decrypting the keypair) , I'm not able to connect to windows instance using remote desktop connection.

Its displaying error message as below.

I'm not able to get where the things are going wrong.

Any suggestions will be of great help.

Thank you.

Answer 1

The reason for the connectivity issue is as below:

The route table associated with the subnet(in which instance is launched) is not configured for the target of internet-gateway. So I have used the private subnet logically instead of public subnet.

Since I didn't use the VPC wizard(which will auto-configure the needed routes) to create/configure VPC and subnets, I have missed it. Thank you all for your time and suggestions.

Answer 2

Just go to a security group and select RDP and open it for 0.0.0.0/0(or limited). it should work.
