title: Connecting RDS SQL Server from AWS EC2 SQL Server Management Studio
body: <p>I am unable to connect my RDS SQL Server instance from my AWS EC2 instance.</p>
  
  <p>I have installed SQL Server Management Studio on my AWS EC2 Windows Server 2019 instance. </p>
  
  <p>I am neither able to ping my RDS endpoint from that machine nor able to connect using SSMS. In the security group inbound rules for RDS I have entered IP of my EC2 instance under all traffic option, also tried using SQL Server option in security inbound rules.</p>
