Zigbee issue devices stop working

I setup several zigbee door contact sensors, that works properly for about 30 days sending notifications that the door was closed or open, now I am not getting any notifications, when I run the automations from the dashboard I received the notifications, but not when the door is opened or closed , what is causing the problem , what can correct this issue

a battery change?

Logs? A description of which zigbee implementation?

Ok will do , do batteries for thee devices have a short life span usually

You haven’t even told us what devices.

Where are the logs for these devices located

As I asked before, which zigbee implementation?

It depends on their usage and what condition they had from start.
If the sensors are put in use at the same time, then their battery life could be somewhat identical, and the batteries that come with devices are often half dead at arrival.
