Ubuntu 18.04 Ec2 instance (2GB)

I am setting on Premise habitat in my ec2 instance (for testing). I have set up everything. but when I sign up with Github it shows the following error.  
[![Screenshot from 2021-10-21 15-04-50](https://us1.discourse-cdn.com/flex016/uploads/chef/original/2X/0/03a5f353d1fc47b8506643b4d3971756d2af428a.png)](https://user-images.githubusercontent.com/44102752/138252166-ea59ba7a-a766-4b49-b441-a03776261506.png)

Console shows bad gateway 502 error.

I checked for the log file in builder-API-proxy this is the error that I get.  
`[error] 8540#0: *56 recv() failed (104: Connection reset by peer) while reading response header from upstream,`  
`request: "GET /v1/authenticate/<github_secret HTTP/1.1"`  
Upstream is pointing to `http://instance_ip:9636/v1/authenticate/<github_secret>`

Same error Arise when I search for package name in `/pkgs/core` url.

I already tried this 2-3 times but no luck. also followed the troubleshoot instruction.

`sudo hab svc status` shows everything working(up state). but there is some connection problem between habitat builder proxy and builder.
