Django: Heroku Failing to launch, at=error code=H10 desc="App crashed"
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.
The same error occurs when the gunicorn
package is not installed (in your virtualenv
). Here is a similar traceback as of October 2016:
2016-10-21T08:35:56.041002+00:00 heroku[router]: at=error code=H10
desc="App crashed" method=GET path="/" host=mygreatapp.herokuapp.com
request_id=blablabla fwd="188.73.193.22" dyno= connect= service=
status=503 bytes=
I was so impatient and during the conversion of my local app to a Heroku one (which includes the creation of Procfile
, runtime.txt
, .gitignore
files, installation of dj-database-url
, whitenoise
) I forgot to install the most important package (pip install gunicorn
)!!!
Doing so, H10 error
vanished!
cheers!
