ER6120 V3 DHCP issue

I have a verry anoying issue in my lan and i think its related to the DHCP server from ER6120
below is the network topology
Internet ---ER6120---Cisco SG220- 3xEAP245
All 3 EAP 245 are on omada software controller and provides wireless access. The issue is that some wireless clients gets rejected when trying to get an IP and i see in the log files of the ER6120 the following
DHCP Server rejected the request of the client[MAC: 08:c5:e1:39:30:28 IP: 172.32.0.70]
DHCP Server rejected the request of the client[MAC: 98:da:c4:fc:d3:de IP: 172.32.0.67]
and of course internet or lan access on this clients does not work. Setting a static IP on clients works. Sometimes i see in the DHCP Server reject message the MAC of one of the EAP245 access points - this is really strange since all 3 EAP245 are on static IP.
Also, no fancy configurations, everything is on default, no VLAN or VPNs
Any idea ?
