Solution:
really the problem here was the wsgi file itself, formerly before django 1.3 the wsgi file was named with an extension of .wsgi
, however now in the current versions it will be created with and extension of .py
that is the wsgi file should be a python module
so the file must be hello_wsgi.py
and command must be
gunicorn hello:application -b xx.xxx.xxx.xx:8000
run guncorn with --preload can view the error log, like this
gunicorn app:application --preload -b 0.0.0.0:5000
This will generally give you a more detailed error message.
You don't displayed a full output. It's possibly looks like
$ gunicorn elcarweb.wsgi

However before You view necessary informations:
ImportError: No module named elcarweb.wsgi
In case You view this error, then resolution is run gunicorn with --chdir=/your/app/dir
parameter.
I also had a same error in Ubuntu 16.04, Django 1.11, employing systemd.
My issue was that I had split my settings out into separate files; for example: instead of having all settings in project/settings.py, I have a some settings files like project/settings/dev.py.
I had to update DJANGO_SETTINGS_MODULE in the project/wsgi.py file from:
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings")
to
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings.dev")
