**Ignition 8.3** , in case of a server failover, data from an opened perspective session are freezed and then we have a "No connection" message and after the session can reconnect to the new active node.

Operators would like to be notified more quickly that the data are stale and freezed.  
Can we adjust some settings to have a "No connection" message more quickly ?

Probably **Session Timeout Desktop ?**

A Shutdown script executes when a Session ends due to:

- ...
- Gateway redundancy failing over.

I suppose we can only use **onShutdown session event** to make some gateway scope traits, but we can't show a warning popup in that case because the communication between the gateway and the browser is down. If we need a custom popup to warn operator we have to look at iframe or JS injection with markdown ?
