Websocket error in executing Duo Agent Platform flows (Severity 3)

Problem: WebSocket connections for Duo Agent Platform flows were returning 404 errors, preventing users from running remote workflows.

Impact: Starting January 6, 2026 around 5 AM UTC, all remote workflows using Duo Agent Platform failed with 404 errors.

Causes: A recent update introduced stricter access checks for namespace membership, which caused service accounts used in remote flows to fail authentication if they were not direct members of the required namespace. This resulted in 404 errors for WebSocket connections.

Response strategy: We identified the issue as an update to namespace access logic and developed a targeted fix. The fix was approved, merged, and deployed to production. 404 error rates are now dropping, and remote flows functionality is restored.
