I have a branch have Meraki MX, Switch, AP.
Problem: Meraki MX DNS is working fine (Green) , but Switch and AP are showing bad DNS. so they are in alerting.
This cause user cannot connect to network.
Once i restart MX, everything is back to normal. they are back in green.
Note: Switch and AP management IP is vlan 1, vlan 1 is configured to use upstream dns.
MX firewall WAN 1 DNS is configured based on local telco.
Can it be local telco DNS issue? but how to explain when i restarted the MX, everything is back to green again?
Any chance something is also configured with the MX VLAN1 LAN IP address?
