Help with a virtual ap

Recently I’ve put a switch Mikrotik with a hidden network, so I decide put a virtual wlan, but nobody can connect devices to that interface… they always stays on “getting ip address” and never get into the internet, Any suggestion?

Is the dhcp server reachable by those clients?

Wireless mode: Ap Bridge
Create a DHCP Server on the Virtual Interface

IP - Address - Create IP for Wireless Virtual Interface
IP - DHCPServer → DHCP Configuration

Put interface in the same bridge with wlan.
