Issues deploying the project in django using nginx, gunicorn

[AdnaneSaber]

I would like to deploy this project which works perfectly on localhost or on python manage.py runserver command, when I try to deploy it I read on the documentation on the worker you should add these to gunicorn service which when I do -k eventlet -w 1, it returns 502 bad gateway This is what i'm getting based off https://github.com/miguelgrinberg/python-socketio/tree/main/examples/server/wsgi/django_example This is my gunicorn service

[Unit]
Description=gunicorn daemon
Requires=dev.socket
After=network.target

[Service]
User=myuser
Group=www-data
WorkingDirectory=/var/lib/jenkins/workspace/myproject
ExecStart=/var/lib/jenkins/workspace/myproject/env/bin/gunicorn \
          --access-logfile - \
          --workers 3 \
          -k eventlet \
          --bind unix:/run/dev.sock \
          myproject.wsgi:application

WantedBy=multi-user.target

wsgi.py

import os

from django.core.wsgi import get_wsgi_application
import socketio

from app.views import sio

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myproject.settings')

wsgi_application = get_wsgi_application()
application = socketio.WSGIApp(sio, wsgi_application)

settings.py

...
WSGI_APPLICATION = 'myproject.wsgi.application'
...

If I remove the -k eventlet from the dev.service gunicorn service, the 502 bad gateway goes away and the page keeps loading forever and it returns 504 Gateway Time-out, and if I revert back wsgi.py to it's django by default boilerplate, it shows the page, but the websockets doesn't work and the page keeps sending https://example.com/socket.io/?EIO=4&transport=polling&t=opIU5ZA GET requests, that gets 502 bad gateway
