Seems like the problem is in Gunicorn, so focus on that only.
What's your Gunicorn socket file path? Seems like that's the common problem - as described in length here:
http://stackoverflow.com/questions/28689445/nginx-django-and-gunicorn-gunicorn-sock-file-is-missing

okay so i changed the directory ---per some recommendations in another post about security to this:

unix:/var/log/gunicorn/chrisblog.sock

here is my full gunicorn.service file:

[Unit]
Description=gunicorn daemon
After=network.target

[Service]
User=django
Group=www-data
WorkingDirectory=/home/django/chrisblog
ExecStart=/home/django/chrisblog/myprojectenv/bin/gunicorn --workers 3 --bind unix:/var/log/gunicorn/chrisblog.sock chrisblog.wsgi$
[Install]
WantedBy=multi-user.target

and here is my nginx file

server {

    listen 80;
    server_name 45.32.201.31 pythoncreate.com;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/django/chrisblog;
    }

    location / {
        include proxy_params;
        proxy_pass http://unix:/var/log/gunicorn/chrisblog.sock;
    }
}
