Is CanvasRelay down, or is it just this device/network?

What you may be seeing

• A player, dashboard action, or several screens stop communicating.

What usually causes it

• A single device/network problem.
• A browser/app was closed or suspended.
• A broader API/Cloudflare/service incident.

Do this

1. If only one screen is affected, check that device's power, internet, last-seen, errors, and player state first.
2. If several screens on the same local network are affected but other networks work, investigate that local network/ISP/DNS path.
3. If unrelated networks and the dashboard/API fail together, treat it as a likely service-side incident and avoid destructive re-pair/reset steps on every screen.
4. Settings shows the API health result when the dashboard can reach it; screen diagnostics/recent CR codes can further narrow the failure.

You know it is fixed when

• API health is normal and affected devices resume recent heartbeats/check-ins.

When this is probably a real support issue

• Multiple unrelated networks fail at the same time or API health reports a service dependency failure.
