I'm working on a Hapi server for a ReactJS app but when I try to deploy to Heroku, I get the R10 error "Failed to bind to $PORT within 60 seconds of launch". What is going on? I'm using process.env.PORT. I also tried parseInt() around it. Also tried disabling varying packages. The build is successful always.
In the Heroku logs, I see the console log from the index.js ("Hapi running on ...") but then the R10 error shows up and the server restarts, then crashes.
==>🌎 Hapi Production Server (API) is listening on http://localhost:14316 2016-01-22T15:10:33.947571+00:00 heroku[web.1]: Stopping process with SIGKILL 2016-01-22T15:10:33.947571+00:00 heroku[web.1]: Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch 2016-01-22T15:10:34.737554+00:00 heroku[web.1]: State changed from starting to crashed 2016-01-22T15:10:34.724233+00:00 heroku[web.1]: Process exited with status 137
This all runs fine locally when I run with NODE_ENV=production
