sydney.py: sydney.exceptions.CreateConversationException: Failed to create conversation, received status: 404

i got this error, its weird that i have 404 error code for accessing copilot in python. It was fine few days ago and i dont really use bing chat that much. I’ve tried to switch account (and also changing the cookie) but still got the error

if i go to copilot myself, its all 100% fine. here is my code (same as in the page description)

import asyncio

from sydney import SydneyClient
import os, json

with open("credentials.json") as file:
    credentials = json.load(file)

os.environ["BING_COOKIES"] = credentials["cookie"]


async def main() -> None:
    async with SydneyClient() as sydney:
        while True:
            prompt = input("You: ")

            if prompt == "!reset":
                await sydney.reset_conversation()
                continue
            elif prompt == "!exit":
                break

            print("Sydney: ", end="", flush=True)
            async for response in sydney.ask_stream(prompt):
                print(response, end="", flush=True)
            print("\n")


if __name__ == "__main__":
    asyncio.run(main())
