how do i fix this aiohttp.client_exceptions.WSServerHandshakeError: 401, message='Invalid response status', url='wss://regina-p521at8z.livekit.cloud/agent'

Thanks for reaching out, Localhost. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
The error 
aiohttp.client_exceptions.WSServerHandshakeError: 401, message='Invalid response status'
typically occurs due to an authentication issue, such as a missing or invalid token. Here are steps to resolve this: 1. Verify API Credentials: Ensure the API key and secret are valid and correctly configured. 2. Check Token Permissions: Confirm that the JWT token includes all necessary grants for room access and publishing. 3. Inspect Token Generation: Review how the token is created to ensure it is correctly signed and not expired. For example, token generation in Python might look like this:
Copy code
access_token = AccessToken(api_key="your_api_key", api_secret="your_api_secret")
access_token.add_grant(VideoGrants(room_join=True, can_publish=True))
token = access_token.to_jwt()
If the issue persists, please share details about your token generation process for further assistance. Sources: livekit/livekit_agent_dispatch.twirp.go | livekit-plugins/livekit-plugins-bey/livekit/plugins/bey/avatar.py | src/pages/api/connection_details.ts

i am running the avatar in python, the frontend will call to generate the token. so there is no need for token? the api credetnails are correct

Hey there! Just a quick heads-up: LiveKit needs an access token for every WebSocket connection, even if you’re running an avatar in Python and your frontend is creating the token. This token is super important because it helps authenticate you and includes details like the participant’s identity, the room name, and permissions. If your frontend is handling the token generation, make sure it’s being passed correctly to your Python WebSocket connection method. Without this token, the connection won’t go through and you’ll see a 401 error. If you want a hand with how to pass or integrate the token, just give me a shout—I’m here to help!

That warning 
WARNING livekit.agents - failed to connect to LiveKit, retrying in 0s
basically means the system tried to connect to the LiveKit server but didn’t quite make it, so it’s giving it another shot automatically. Here are a few friendly steps you can try to get things back on track: 1. Network Check: Make sure the agent’s internet connection is steady and working well. 2. Server Status: Double-check that the LiveKit server is up and running, and you can reach it. 3. Configuration Review: Take a moment to confirm the connection credentials and settings are all correct. 4. Logs Analysis: Have a look at the logs to see if there are repeated connection issues or other errors that might give us clues. If you’re still running into trouble after this, just let me know! I’m here to help dig a little deeper. Sources: livekit-agents/livekit/agents/stt/fallback_adapter.py | agents/src/worker.ts
