Flask SocketIO connection faild on production

Question

I just deployed my flask application on development server after i checked that the socketio works well on regular run server and also using gunicorn with eventlet on local, Now i deployed my flask app and it runners well when i open any page (HTTP) like API or so, But when i try to connect to the websockets it says the following error in the console tab in the browser

Firefox can’t establish a connection to the server at ws://server-ip/chat/socket.io/?EIO=4&transport=websocket&sid=QClYLXcK0D0sSVYNAAAM.

This is my frontend using socketio cdn

 <script src="https://cdn.socket.io/4.3.2/socket.io.min.js" integrity="sha384-KAZ4DtjNhLChOB/hxXuKqhMLYvx3b5MlT55xPEiNmREKRzeEm+RVPlTnAn0ajQNs" crossorigin="anonymous"></script>
var socket = io.connect('http://server-ip/chat/send/', {"path" : "/chat/socket.io"});

I set "path" here to the correct socket.io url, If i tried to remove it and just type the url it gives

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://37.76.245.93/socket.io/?EIO=4&transport=polling&t=NrcpeSQ. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

So i added it to redirect it to the correct url but it can't connect it using ws as shown above

I am using this command on server to run flask

gunicorn --worker-class eventlet -w 1 --bind 0.0.0.0:8000 --timeout 500 --keep-alive 500 wsgi:app

and this is my wsgi file

from chat import app
from dotenv import load_dotenv, find_dotenv
from flask_socketio import SocketIO
from messages.socket import socket_handle

load_dotenv(find_dotenv())
app = app(settings="chat.settings.dev")
socket = SocketIO(app, cors_allowed_origins=app.config['ALLOWED_CORS'])
socket_handle(socket)

The 'socket_handle' function just appends the join and message_handle functions with socket decorator to them, I think something is preventing the server to work on ws but i don't know why

I know that this need to be run as ASGI not WSGI but as socketio docs says i think using eventlet will solve this, But i also tried to replace my wsgi.py file to this

from chat import app
from dotenv import load_dotenv, find_dotenv
from flask_socketio import SocketIO
from messages.socket import socket_handle
from asgiref.wsgi import WsgiToAsgi

load_dotenv(find_dotenv())
apps = app(settings="chat.settings.dev")
socket = SocketIO(apps,  cors_allowed_origins=apps.config['ALLOWED_CORS'])
socket_handle(socket)
asgi_app = WsgiToAsgi(apps)

And when i run Gunicorn command i get this

gunicorn --worker-class eventlet -w 1 --bind 0.0.0.0:8000 --timeout 500 --keep-alive 500 wsgi:asgi_app
