If your gateway APs are reporting the following alerts:

Alert: This device is having difficulty contacting the Meraki Cloud
This gateway is disabled. Its Domain Name Service (DNS) configuration is not working.

Your DHCP server may be incorrectly configured to use DHCP Option 5 "Name Servers" instead of DHCP option 6 "DNS servers." Meraki access points support DHCP Option 6 Domain Name Servers. DHCP Option 5 is for setting Internet name servers and is not supported.

Please review your DHCP server setup guide for assistance with configuring DHCP options.
