Remote mysql database connection failing using mysql navicate

1.** Security Group Issues:** By default, RDS instances are secure and don't allow connections from anywhere. You need to configure your security group to allow inbound connections on port 3306 (the default MySQL port) from the specific IP address or IP range where MySQL Navigator is running.

2. Incorrect Credentials: Double-check your username, password, and database name
3. RDS Instance Status: Make sure your RDS instance is in the "available" state. You can check the status in the AWS Management Console.
