wireless station, dhcp-client not working

RouterOS Wireless Networking

My rb133 ist associated to a wlan ap. With static assigned IP addresses everything is working fine. If I enable dhcp-client on wlan1 interface, it doesn’t work. Status is searching:

[admin@MikroTik] > /ip dhcp-client pr detail 
Flags: X - disabled, I - invalid 
 0   interface=wlan1 host-name="mikrotik" add-default-route=yes 
     use-peer-dns=yes status=searching...

On the dhcp-server I’m getting the DHCP offer and it responds with a DHCP discover to FF:FF:FF:FF:FF:FF. So far so good. But the DHCP discovers obviously don’t make their way back to the rb133. The tcpdump output from the dhcp-server side:

21:45:03.811239 00:05:3c:07:2b:2f > ff:ff:ff:ff:ff:ff, ethertype IPv4 (0x0800), length 346: 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from 00:05:3c:07:2b:2f, length 300
21:45:03.814232 00:0d:93:72:d4:d8 > ff:ff:ff:ff:ff:ff, ethertype IPv4 (0x0800), length 342: 192.168.200.1.67 > 255.255.255.255.68: BOOTP/DHCP, Reply, length 300

The dhcp-server is working fine, because my notebook get’s an IP address from it perfectly when it is associated to the mentioned AP.

Any hints?

No one who can help? Forgot to mention that I’m using the latest stable software branch 2.9.46.

And the output from the ISC-DHCP Server:
