I am integrating with Kite Connect (Python client) and running into a consistent WebSocket authentication failure.
REST authentication works generate_session() succeeds and returns a valid access_token. kc.profile() succeeds with that token.
WebSocket fails The WebSocket handshake to wss://ws.kite.trade?api_key=API_KEY&access_token=ACCESS_TOKEN consistently returns: HTTP 403 with body: {"status":"error","message":"Authentication failed."}
This happens even immediately after a fresh login + token exchange.
I am not asking for coding/debugging help — I want to confirm whether this API key/user/app has WebSocket streaming enabled, or if there is a server-side restriction or entitlement issue.
