Django: Heroku Failing to launch, at=error code=H10 desc="App crashed"

Trying to Launch an application on Heroku and for the past few weeks I just cannot seem to get past this error. I setup my repo correctly and everything pushed to Heroku via git then when I open my site via the link given to me, I see the application failure error message. I view my logs but cannot seem to decipher where the error is coming from or how to begin to debug. If anyone can help that would be amazing! Thank you!

My log message below:

Answer

It looks like heroku can't start the webserver and so changed the app status to crashed. Everytime when I get this error code the Procfile was misconfigured or had errors.
