ConnectionWarningWatchdogTimeout

Post by yassin2403 »

Hallo,

the connection state changes to this "ConnectionWarningWatchdogTimeout" then changes to "ConnectionErrorApiReconnect". is the a way to avoid this Error.

Thanks,

Yassin

Hello Yassin,

the UaExpert does a cyclic read (every General.WatchdogTime milliseconds) on the ServerStatus with a timeout of General.WatchdogTimeout to detect connection interruptions. If this takes too long, the connection status changes to ConnectionWarningWatchdogTimeout and the call is repeated with twice the configured timeout. If this also fails, the connection status changes to ConnectionErrorApiReconnect and a reconnect to the server is triggered.

If the server takes too long to respond to these watchdog reads, it might help to increase the configured values in the UaExpert settings. As the default values are 5 seconds, you might also check the server for problems, as the server should be able to respond to a simple read in much less time.
