aws rds mysql 连接,AWS RDS：使用Navicat连接

I have just created RDS Instance in N.Virginia & trying to connect that database using Navicat.

But I'm unable to connect it.

After searching over internet I came to know that we need to configure Security Groups. But in my case there is a notification :

Your account does not support the EC2-Classic Platform in this region. DB Security Groups are only needed when the EC2-Classic Platform is supported. Instead, use VPC Security Groups to control access to your DB Instances. Go to the EC2 Console to view and manage your VPC Security Groups. For more information, see AWS Documentation on Supported Platforms and Using RDS in VPC.

Please help me out to resolve the issue. And also N.Virginia is what the AWS assigned automatically. It is good to opt for N.Viginia in Free-tier.

I would probably not advised to get a direct link on your RDS Database
