amazon web services - AWS ECS container - 500: Internal Server Error

Question

I am getting the 500:Internal Server error while trying to access the ECS container application from outside the container. The application has a heartbeat page and I can access the URL fine from the container itself.

curl -kv https://localhost/xxx/heartbeat
* About to connect() to localhost port 443 (#0)
*   Trying 127.0.0.1...
* Connected to localhost (127.0.0.1) port 443 (#0)
* Initializing NSS with certpath: sql:/etc/pki/nssdb
* skipping SSL peer certificate verification
* SSL connection using TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
* Server certificate:
*

*<h1>xxx is alive</h1>*

However, If I try to access the same URL from the ECS host instance from a my local computer browser, it fails:

 curl -kv https://0.0.0.0/xxx/heartbeat
*   Trying 0.0.0.0...
* TCP_NODELAY set

I have tested the docker container on my local machine and it works without any issue so it's not a problem with the image. My current setup involves: ECS Cluster ECS Service & ECS Task definition I have tried using a different task definition that has a different docker image and it works fine. I have tried increasing soft memory limit among other things on my task definition and that didn't seem to help.

Any help/advice would be much appreciated.

Thanks!
