Unable to RDP into Windows EC2 Server

After creating my Windows EC2 instance, I have been able to connect to the server using RDP. However, the last time I connected to the server, I created an inbound rule for ports 80 and 9443 to test an application. The test was not successful, so I put off all the firewalls to test again, still the test was still unsuccessful. After that, I clicked the 'restore settings' available on the Windows firewall page to put all the firewalls back. It was after this action that I have not been able to connect back to the server using RDP.
