Tailscale connecting to AWS RDS Aurora

Tailscale version
1.30.1
Your operating system & version
amazon-linux

Hey Tailscale team,

I have setup a Tailscale Bastion host and have it advertising my entire VPC (10.0.0.0/16)

From psql on the bastion, I am able to connect to my AWS Aurora RDS instance no problem. However when attempting to connect from another system in my tailnet, this service is unavailable. All other instances in my VPC (when connected via compute.internal) work fine.

AWS Aurora is more managed than normal RDS and the hostname is amazonaws.com instead of compute.internal and it still returns an IP within my VPC even externally.

Any assistance here would be appreciated, thanks!
