Unable to initiate kobotoolbox in an EC2 instance

Here’s my experience installing kobo-docker on a fresh Linode instance with 2 GB RAM. It’s not EC2, but the steps should be largely the same. At the time that you tried your install, kobo-docker may have assumed it was behind a load balancer or reverse proxy. It now supports running without one, and it can also generate SSL certificates with Let’s Encrypt automatically.
