Internal Server Error 500 when deploying Django Application to Elastic Beanstalk

Question

I followed meticulously the official AWS guide to deploy a Django App to Elastic Beanstalk ( https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create-deploy-python-django.html ) for a school project. It is working locally, but when I try to deploy it shows a 500 Error message. I went through many adjustments in my code but they don't seem effective. The AWS dashboard shows one warning that says: Environment health has transitioned from OK to Warning. 100% of the requests are failing with HTTP 5xx. Could it be a timezone problem as I am currently in Europe?

I tried to change debug mode from true to false, but I don't think that's the problem. the I truly do not understand why it's not working, I never got an error in the execution in the terminal and it always deployed everything correctly. It is just not showing the web page for some reason.

Answer 1

Did you resolve it? I struggled for weeks but with a 502 after following exactly the instructions.

Then I found this post and deduced it was a typo or outdated instructions ( */wsgi.py should be *.wsgi:application ).

Created a pull request to AWS docs and they've updated since.

Answer 2

I was having the same problem, until I realized I hadn't included the following line in my settings.py file:

ALLOWED_HOSTS = ['eb-django-app-dev.elasticbeanstalk.com'] 

Replacing the link inside the brackets with my own custom application link, as stated in step 5 of the tutorial.

After saving the file and committing, I was able to get rid of the 500 error.

Answer 3

I was trying to deploy my Django Rest Api to Beanstalk by following this documentation . And I encountered the same Status Code 500 error.

I managed to solve this problem by making below two changes:

1. AWS Beanstalk's python 3.6 environment doesn't seem to work well with latest Django versions. So I created a new python 3.7 environment using this command.

    eb init -p python-3.7 django-tutorial

2. Changed WSGI Path to :

   WSGIPath: YourDjangoProjectFolder.wsgi:application

All other things are same as described in that documentation.
