django app in heroku getting worker timeout error

Heroku requests are limited to 30 seconds, if the request take longer than this the router will terminate the request

You can increase the LOG LEVEL of gunicorn to see if there's some error in your process

Example of Procfile with timeout increased to 15 sec

web: gunicorn myproject.wsgi --timeout 15 --keep-alive 5 --log-level debug
