Misconfigured DNS

[Ladiesman21ch]

The problem I am currently experiencing is hampered by the Switch Core and several other Distribution Witches experiencing DNS Misconfiguration problems, sometimes the Switch experiences No Connectivity and this has happened continuously and for the past 2 days this problem has not been resolved even though I have changed the DNS to Google DNS on WAN 1 and WAN 2 but there is no change, it even spreads to other Meraki Access Points.

Same response as per your other post:

This is probably as simple as your firewall is blocking DNS traffic from your switch/Meraki management VLAN.  Start at the firewall and see what’s being blocked.

This error usually is not lying.  There may be an issue where the interface IP of the Meraki device cannot reach the configured DNS server.  Usually this is an upstream firewall or isp issue.  Or it can be that the normal vlan you configured your devices on is not able to reach dashboard and your Meraki devices are on a different subnet.
