Monitoring Tools Univention UCS

Hi everybody, i got a problem regarding the installation of ucs dashboard database and prometheus alertmanager. So when the alert in dashboard database are firing, in the prometheus alertmanager there is none of the group alert that got fired so there is no notification that are sending to the email. Is using a replica node as the one which all of this app installed had any effect at all?? or because there are several server whose got different version that causing this problem??

Thank you for all your attention
