Finally, you should rule out if there are any DNS resolution issues: Out-of-the-box, resources in a VPC will not resolve to your on-premise DNS. Like in a typical non-serverless applications you maintain a pool of connections to database and avoid opening a connection prior to issuing the query (or transaction) - much like what RDS Proxy offers.
