While I'm connecting to ws_url sometimes the connection is working fine but in few cases it is connecting and then closes immediately.
Is there something out of these 3 points:
1.Only have frontend connect to the WebSocket 2.Use a different backend control mechanism (REST API, separate WebSocket endpoint) 3.Ensure only one client connects at a time (coordinate frontend/backend)

Session ID for reference:LiveAvatar session: 971f95e6-b861-4fb2-8818-ae6f816abc0f
