How can I connect to my serverless RDS instance from the public internet?

Question

Using Aurora on RDS serverless

• VPC is connected to an ACL that allows traffic on 3306
• routing table connected to IGW that routes traffic to the public internet

Tried connecting to the endpoint listed in "Connectivity & security"

• Cannot ping my endpoint
• Cannot telnet to the endpoint
• Can resolve the endpoint
• Cannot connect from C#
• Cannot connect from mysql -h ENDPOINT 3306 etc
