I have a windows DHCP server in VLAN 10 and I have wireless clients in VLAN 288. The VLANs are defined in my Juniper EX-4600 and the VLANs are tagged/trunked all the way to the Meraki APs.
[DHCP]---[EX-4600]---[EX-4300]--[HP5130]---[Meraki APs]
There are VLANs that are working and VLANs that do not and they all seem to have the same configuration with the exception of the subnet.
The only thing that I have found in searching for a solution was on the juniper KB that said to configure IP helpers, but none of the other VLANs have that and they work, so I don't think that is the solution.

Best Answer
Your configuration looks correct from a dhcp-relay perspective.
If swapping the VLAN for 236 works, then the issue may be with the DHCP Scope for those two subnets on your DHCP server - check that your subnet mask on the server matches the irb interfaces that you have defined on the EX.
