Icinga Daemon restart fails

Hello guys,
I have recently renamed my master node and ever since i am not able to restart my icinga daemon.
I have updated the zones.conf file to have the current fqdn of the node.
The Error i get is: “Endpoint object for [OLD NODE NAME] is missing”, Even though i cannot find a reference to the old name.
Unfortunately I cannot add screenshots because i work in a close network.
Would appreciate your help.

Thanks in advance,

Maybe this helps.
