I’m deploying my Django app to Heroku, but after following all the necessary deployment steps, I’m facing persistent issues. These errors appear after deployment, and I’ve tried various troubleshooting methods but haven’t resolved the problem.
Here’s a summary of the situation and the steps I’ve taken:
Error Overview:
- Logs show:
- Method=GET path=“/” and path=“/favicon.ico”
- status=503 service error
- no web processes running
- HTTP Status: Method Not Allowed
Steps Taken to Resolve the Issue:
-
Created a Procfile in the root directory of my project containing:
web: gunicorn Django_project.wsgi --log-file -
- I verified that the spelling of
Procfile
is correct (with a capital ‘P’). - My requirements.txt file includes gunicorn, Django, and all other dependencies.
- I verified that the spelling of
-
Pushed to Heroku:
-
I committed all changes and pushed to the Heroku remote using:
-
bash
git push heroku main
-
-
Run Migrations:
-
Successfully ran database migrations on Heroku using:
bash
heroku run python manage.py migrate
-
-
Scaled Dynos:
-
Attempted to scale the web dynos using:
bash
heroku ps:scale web=1
-
Result: Received an error stating no web processes running.
-
-
Django Settings Configuration:
-
Added the Heroku app URL to ALLOWED_HOSTS:
python
ALLOWED_HOSTS = [rentaltz.herokuapp.com] -
Configured static files and Whitenoise correctly as shown:
python
MIDDLEWARE = [
‘django.middleware.security.SecurityMiddleware’,
‘whitenoise.middleware.WhiteNoiseMiddleware’,
‘django.contrib.sessions.middleware.SessionMiddleware’,
‘django.middleware.common.CommonMiddleware’,
‘django.middleware.csrf.CsrfViewMiddleware’,
‘django.contrib.auth.middleware.AuthenticationMiddleware’,
‘django.contrib.messages.middleware.MessageMiddleware’,
‘django.middleware.clickjacking.XFrameOptionsMiddleware’,
]
-
-
Checked Logs:
-
The Heroku logs display the following message:
bash
at=error code=H14 desc=“no web dynos running” -
It seems that the web dynos are not properly activated.
-
- I’ve followed best practices for setting up the project for Heroku (e.g., using
gunicorn
, adding static file handling with Whitenoise, and ensuring the correct environment variables). - I’ve tried different branches and even attempted a full redeployment but continue facing the same issue.
- Locally, the app works perfectly fine.
Could someone kindly help me understand why I’m getting these errors, specifically the “no web processing” issue? Is there something wrong with my configuration, or am I missing a critical step? Any guidance or feedback on my approach would be highly appreciated.
