Hello everyone, i'm trying to make a python websocket using websockets library also flask

so basically i have this ->
async def main():
url = os.environ.get('RAILWAY_URL', 'localhost')
port = os.environ.get('RAILWAY_PORT')
print(f"WebSocket server is running at: wss://{url}:{port}")
asyncio.ensure_future(ping_pong())
asyncio.ensure_future(websockets.serve(handle_connection, "0.0.0.0", 4505))

app.run(host='0.0.0.0', port=int(os.environ.get('PORT', 5000)))

asyncio.run(main())
async def main():
url = os.environ.get('RAILWAY_URL', 'localhost')
port = os.environ.get('RAILWAY_PORT')
print(f"WebSocket server is running at: wss://{url}:{port}")
asyncio.ensure_future(ping_pong())
asyncio.ensure_future(websockets.serve(handle_connection, "0.0.0.0", 4505))

app.run(host='0.0.0.0', port=int(os.environ.get('PORT', 5000)))

asyncio.run(main())
functions functions etc.... when i go to my website hhr-bot-api.xyz i get the empty flask page but the thing is how do i connect to the websocket server? the railway terminal doesn't show anything out of common i used everything. wss://hhr-bot-api.xyz:4505 / ....... nothing looks to work.

you can't expose multiple ports, you need to have the websocket and http server listening on a single port

unfortunately I'm not a python developer, so I'm not much help here, but I know for an absolute fact that this can be done

some things that might help, you may consider using quart instead of flask: https://flask.palletsprojects.com/en/2.3.x/async-await/#when-to-use-quart-instead i connect to my websocket like this (no port)
let host = window.location.hostname;
let socket = new WebSocket(`wss://${host}/ws/con`);
let host = window.location.hostname;
let socket = new WebSocket(`wss://${host}/ws/con`);
and it seems to be working, but im still in testing phases. a fetch interrupts this connection & that may be a problem with my code. in quart you can define a websocket route like this
@app.websocket('/ws/con')
async def websock():
pass
@app.websocket('/ws/con')
async def websock():
pass
