Icinga2 deletes the acknowledgment after expire time. but the re-notify is not happening


I have an Icinga2 setup with version: r2.12.5-1 and Icinga Web 2 version -

I have created a setup with some service/hosts checks with the notifications enabled and this is working fine.


The issue that I face is, even after the acknowledgment expiry time is expired, Icinga2 is not clearing the acknowledgments and not enabling the re-notifcations.

But from the history and debug logs, the acknowledgments has been removed. But, still re-notifications are not getting triggered.

Please suggest me on this.
