Simple Node.js app gets 502 Bad Gateway

Question

Hello
I push a simple Node.js app that should return index.html on the 
[main domain](http://demo-game.eu-west-1.elasticbeanstalk.com/)
and listens API on main domain/api

Repo locates on [Github](https://github.com/uaKorona/tb-game) and I tested it locally - everything works fine

I also checked inbound rules and there is presented a rule for 80 port 
![Enter image description here](/media/postImages/original/IMk79_ll_2SW6KHcT5qDWQnQ)
 
What would be a reason of 502 error ?

Accepted Answer

Aws Elastic Beanstalk does not allow running your Node.js app directly on the port 80.

I have solved my issue by adding Beanstalk config file to the project root: 
.ebextensions/app.config

```
option_settings:
  aws:elasticbeanstalk:application:environment:
    PORT: "8080"
```

And re-config my Node.js app to port 8080.

**Now that is working inn the next way:**
I open app URL in browser -> Nginx gets request on port 80 and send in to myApp on 8080
 
P.S. Also need to add an inbound rule for port 8080;
