Guest WiFi can't get IP address (Sonicwall/Aruba/Ruckus)

I have 2 networks/sites that are pretty similar, but only 1 is working properly.

Network1:

• Sonicwall TZ270
• Aruba 1930 8G PoE switch
• Ruckus R320 Unleashed AP
  • Corporate and Guest WiFi SSIDs

Network 2:

• Sonicwall TZ400
• Aruba 1930 48G PoE switch, Aruba 1930 8G PoE switch
• Ruckus R550 (x3), Ruckus R320 unleashed APs
  • - Corporate and Guest WiFi SSIDs

Network/Site 1 is working as expected.

Network/Site 2 is working for wired clients, and Corporate WiFi clients. Guest WiFi is not working on Network 2. Devices are unable to get an IP address.

In both networks I have the Sonicwall configured with a virtual interface. X0:X50 in it's own zone.

In both networks I have a DCHP scope configured for X50 on the Sonicwall.

How can I troubleshoot why Network 2 is not passing DHCP info on to the clients on the guest WiFi.

I have gone through the setup on each network and made sure that the config on the Sonicwall, Aruba and Ruckus gear is the same on both networks.
