Problem with Timerweidget, or just operator error?

I have created a timer in the app. This is done correctly and everything is fine. When the timer expires and I disconnect from the local server, now enter a new timer, and reconnect to the local server, the new timer will not run. Had reset the timer in the app and re-entered. Is it up to me or why does not the new timer start?
Here is the sketch I use.

The red dot above can be forgotten, because 1 ESP8266 is not connected. The other 6 but already

mhhh? Strange, I tried again to set a timer and now it has worked again. How long is the time to set a new timer after one expires? I mean put a new one manually. Disconnect local servers, set timers and then reconnect locale servers
