Start by reproducing the stalled conversation and inspect the GET requests to /api/v2/extendedAgent/workspace/sandbox-status and /api/v2/incidentManagement/checkConnectivityDetailed for the reported threadId. Check the service routing or request logs to determine why both endpoints return 404; done means the conversation receives an agent response instead of stalling.
