I have an Aurora cluster in RDS and a Lambda Function.
- Both are assigned the same VPC.
- Both have the same subnets (us-east-1 a-f)
- Both have the same security group assigned
- Lambda is assigned a role with AmazonRDSFullAccess, AmazonVPCFullAccess, AWSLambdaVPCAccessExecutionRole
When I run the lambda instance, I get connection timeout when trying to connect to Aurora. I'm able to access Aurora locally (with access key added to aws configure).
Any ideas what else I can check for why lambda wouldn't have access to the instance? Thank you
