Why doesn't DHCP issue an ip address?

Question

Mikrotik

Hello, I have a question about setting up the RB3011 router.
The point is.
There is a router and 2 dozen RB951 access points, everything is set up in CAPS MAN, everything works, the task arose to temporarily install a TP-Link WA901 router, it has a MultiSSID function, it can broadcast several networks. I brought a lanyard with a VLAN tag to the TP-Link point, VLAN 9, VLAN40, VLAN7. If everything is fine with VLAN 9.7 networks (clients receive ip), then clients from VLAN 40 cannot get an ip address from DHCP, the only difference between networks is that VLan 40 is in BRIDGE.
My configuration is https://pastebin.com/15gbEm26 The

question is why is it not getting an ip address.

Answer 1

Whether instead of on the corresponding bridge it is necessary to weigh the IP address?
add address=172.16.40.1/24 comment="Stage 4" interface= BridgeStage4 network=172.16.40.0
