I am trying to deploy a django application to AWS ElasticBeanstalk. I am working on a Linux machine. It all goes well but when deployment is done I get "502 Gateway Error". From a deep search I found that people with the similar problem created Procfile to the root directory of the project and added the following to that: "web: gunicorn--bind :8000 --workers 3 --threads 2 applicationName.wsgi:application". I tried that but then I get "ServiceError - Failed to deploy application." Any clues on that?
