I have an RDS with multiple read replicas. In order to load balance the available read replicas, I used Route53's weighted hosted zone. I use this link for doing that: AWS Read Replica
After completing the steps provided in this link, I could connect to the RDS locally (after whitelisting my local IP). But when I try to connect to it from an EC2 server, it is giving the error:
ERROR 2005 (HY000): Unknown MySQL server host 'test.influsoft-dev-rds.menerva.io' (0)
I have tried whitelist both the EC2 machine's public and private IPs. Not sure, what is causing the issue.
But, when I tried opening the MySQL port to the public (0.0.0.0/0,::/0), I can connect to it. What is the issue? How can I resolve it.
