Network Issues

Most network failures fall into discovery, firewall, or host-alias consistency problems.

Nodes Not Appearing

  • Verify nodes are on reachable network interfaces.
  • Check multicast handling (239.2.2.2:3012).
  • Confirm firewall allows WATCHOUT services and required UDP ports.

Node Appears but Goes Stale/Offline

  • Check switch stability and cable quality.
  • Verify host is not sleeping/power-throttled.
  • Confirm process-manager services are still running.

Director/Runner Mismatch Warnings

  • Ensure all nodes are attached to the intended Director.
  • Clear stale show state on nodes if needed.
  • Re-run a controlled startup sequence before rehearsal.

NTP/Sync Instability

  • Confirm Director and runners use consistent time strategy.
  • Check NTP reachability and drift.
  • Resolve time sync warnings before running synchronized playback.
