Node.js app in AWS Elastic BeanStalk can't connect mongodb atlas via privatelink

Hi,

I have been following these instructions and I can’t get connection to worg between my elastic beanstalk Nodejs app and DB. I have VPC setup in my aws enviroment and my elastic beanstalk app is in same VPC. I created interface endpoint in that same VPC (followed with this instruction Connecting Applications Securely to a MongoDB Atlas Data Plane with AWS PrivateLink | AWS Partner Network (APN) Blog). If I whitelist elastic beanstalk IP then connection works, so I assume my connection string is correct, but if I remove that IP from atlas whitelist then connection doesn’t work. I have test many thing but I can’t get privatelink connection work.
