Smoke HHH :
I am trying to run a Spring Boot app on Heroku. I have followed their tutorials and tried to deploy my app but for some unknown reason it keeps failing.

2019-11-08T12:24:00.589583+00:00 heroku[router]: at=error code=H20 desc="App boot timeout" method=GET path="/" host=progresstrackerapp.herokuapp.com request_id=68c7754f-2c39-4cf8-b207-426af344f40c fwd="xxx.xxx.xxx.xxx" dyno= connect= service= status=503 bytes= protocol=https
I edited out my IP from the text. Any idea what might cause the timeout?
EDIT 1: Some things i did: I added the Procfile by myself in the root directory of the app since without it my app would crash
web java -jar target/progresstrackerapp-0.0.1-SNAPSHOT.jar
Also for the commands I did :
git add .
git commit -m "s1"
git push heroku master
Build of the app was fine and no problem appeared there
heroku ps:scale:1 // this resulted in the problem
EDIT 2:
I found the problem.It seems that I needed to specify an environment variable PATH. Heroku needs this variable to be able to deploy on it since it is the developer's job to include it. That is what fixed it for me.
codefinger :
Make sure you’re binding to the correct port by passing -Dserver.port=$PORT to your Procfile command
