Why am I unable to connect to my t2.micro after stopping and starting again?

I'm new to aws and set up a free tier ec2 instance (t2.micro, windows) yesterday. I just wanted to stop my instance and check if my data is persisted on EBS attached to the instance. I stopped the instance and after a couple of minutes, I started it again. The aws management console shows that the instance is running and passed the two checks. But while connecting with the same RDP file which worked earlier, now I'm receiving the following error:

[Window Title] Remote Desktop Connection

[Content] Remote Desktop can't connect to the remote computer for one of these reasons:

1. Remote access to the server is not enabled
2. The remote computer is turned off
3. The remote computer is not available on the network

Make sure the remote computer is turned on and connected to the network, and that remote access is enabled.
