Hello Rene,
Is the client-identifier configured on the dhcp server is not the mac address of the dhcp client? Is it a different value?(real world)
I tried to configure the “ip address dhcp client-id fa0/0” on the dhcp client but it’s not getting the correct ip im expecting. I already have a dhcp pool for it on the dhcp server.:
DHCP SERVER:

no ip dhcp use vrf connected
