App Runner Health Check fails although Application logs show already receiving the request.

Question

I am trying to deploy a new App Runner service. I am using aws cli such that I can configure the health check to use HTTP. I make it to use HTTP and port 8080, and a custom path "health-check/". 
In my application logs, I will print the request received on this path and I am able to see it being printed, meaning I successfully received the request. The response I return is plain text "OK". 
But the service creation always fails with error

Hi @Hari, to provide more information, I managed to fix this issue by only doing one thing, that is changing my port from 8080 to 80. This plus that I can confirm my application can receive requests at 8080, making me think the 8080 port is blocked for egress data. Can you check with the AppRunner team whether that is the case and if yes why? thanks
