I am using default VPC and created RDS MySQL instance (Publicly Accessible: Yes) with newly created db security group. I have given Inbound/Outbound rules as All Traffic, ALL, ALL, and Source = 0.0.0.0/0 and used this security group for MySQL DB instance.
I have disabled Windows Firewall. Still I cannot connect to my DB End point using hostname and port 3306 via telnet and MySQL Workbench. In MySQL Workbench, I'm getting 10060 error and telnet says Could not open connection to the host, on port 3306, connect faild.
What is still missing?
