sock failed (2: No such file or directory) - django + gunicorn + virtualenv + centos7

I am trying to deploy a Django application on CentOS7 using gunicorn and ngnix to handle the requests.

I followed an internet guide (Digital ocean) for CentOS7 (see URL below), I followed the guide as close as possible and when it is supposed that I should see the Django application, nginx throws me a 502 error.

Apparently something is wrong with gunicorn, it does not create a .sock file, I do not know how to fix this problem.

SO: CentOS 7

Python: Python 3.6 (Running Django with a virtualenv python3.6)

Django: 2.0

Gunicorn: 19 ....

nginx

SGBD: SQLite3 (I do not need MySQL or another DBMS for now)

This is the error that shows the nginx log

2018/01/07 02:15:05 [crit] 1284#0: *1 connect() to unix:/home/django/reynaldev_services/reynaldev_services.sock failed (2: No such file or directory) while connecting to upstream, client: 192.168.1.104, server: 192.168.1.105, request: "GET / HTTP/1.1", upstream: "http://unix:/home/django/reynaldev_services/reynaldev_services.sock:/", host: "192.168.1.105"

This is the error that shows gunicorn

I used this guide: Digital Ocean

In /etc/systemd/system/gunicorn.service

[Unit]

Notes: Nginx is running smoothly

SELinux disabled

Firewall disabled

Running Django (using python manage.py runserver .....) runs without problems

Running gunicorn --bind 0.0.0.0:8000 myproject.wsgi: application I can access without problems

Running from the user django (sudo su):
