Failed to start gunicorn.service: Job for gunicorn.socket failed . Ubunto 18.04 TSI

Question

Hello guys I am in need of help with this situation because I have tried several solutions and for my current level of experience I am not able to fix this error and deploy in the app.

I’m following parts of that step by step digitalocean but at some point after preparing practically the whole environment I’m having this problem.

I believe the file . socket

sudo nano /etc/systemd/system/gunicorn.socket

[Unit]
Description=gunicorn socket

[Socket]
ListenStream=/run/gunicorn.sock

[Install]
WantedBy=sockets.target

Then I set up . service already formatting for my project

sudo nano /etc/systemd/system/gunicorn.service
[Unit]
Description=gunicorn daemon
Requires=gunicorn.socket
After=network.target

[Service]
User=guilhermenog
Group=www-data
WorkingDirectory=/home/guilhermenog/projetoagenda
ExecStart=/home/guilhermenog/projetoagenda/venv/bin/gunicorn \
      --access-logfile - \
      --workers 3 \
      --bind unix:/run/gunicorn.sock \
      agenda.wsgi:application

[Install]
WantedBy=multi-user.target

I tried to activate using the command

sudo systemctl start gunicorn.socket

I got this error message

Job for gunicorn.socket failed.
See "systemctl status gunicorn.socket" and "journalctl -xe" for details.

Soon I ran the code "systemctl status gunicorn.socket"
