`I have a flask application that has a an healthcheck https route /my-route and I want my socket connection to get established at /my-route/socket , when i configure the code accordingly and build docker image and run locally, the connection established on ws://localhost:3090/my-route/socket
but after deploying the image to ECS service it does get connected on wss://dev-server/my-route/socket .

I have tried almost everything even updated the listener rules of the ALB.
I still get 503 from server. Am I missing any configurations on server or anything ?
The main thing is I can establish a connection if i do-not specify any route to sockets which is is
on “wss://dev-server”.
Need some help here.

Here is my app.py code snippet –

import eventlet
eventlet.monkey_patch()
from flask import Flask, request
from flask_socketio import SocketIO, send, emit
from chat import *

from dotenv import load_dotenv

socketio = SocketIO(app,cors_allowed_origins="*",path='/my-route/socket')
ChatSessions = {}
mongodb_uri = os.getenv("mongodb_uri")
db_env = os.getenv("db_env")
port = os.getenv('port')
client = pymongo.MongoClient(mongodb_uri)
db = client[db_env]
career_coach_data = db['career_coach']


def setup_chat(user_id):
    sid = request.sid
    user_doc = career_coach_data.find_one({'user_id': user_id})
    ChatSessions[sid] = {
                        "user_id":user_id,
                        "chat_instance":Chat(user_id=user_id),
                        "user_doc":user_doc if user_doc else None

        else:
            new_user_doc = {'user_id': meta_data['user_id'], 'data': [user_message, coach_reply]}
            career_coach_data.insert_one(new_user_doc)
        
    else:
