Client can't reach Gateway and can't get IP from DHCP

[gary_the_network_guy]

So something strange happened, basically out of nowhere clients in a vlan can't reach their gateway and can't get a IP address from our DHCP. I looked into it and checked if all VLANs are configured and port configuration, I checked the output from "show spanning-tree vlan 110", it seems fine, my core is roout and all ports are forwarding, the vlan exists on all switches between core and access, so I am out of ideas. Any help?

I was in the middle of a migration, the accesspoints were in Flex connect mode and also the WLC was learning mac addresses from the accesspoints and also from the port-channel. Thank you all for your help.
