Regarding alert "DNS is misconfigured" on MR

[CHGR]

Our AP is now connecting the internet via Proxy and Proxy sends DNS query to outside DNS server and it handle the name resolution curretly.

AP can not connect outside DNS server directly and we configure ip address of internal DNS server in our AP and we configured internal DNS server provide lookup for meraki.com, google.com and yahoo.com.

(Invers query was responded as server failure but support team said it's not related to the alart.)

However, an alert message as "DNS is misconfigured" has always appeared on the Dashboard.

Whatelse can we do for turning off this alert?

Configured it for the AccessPoint (Wireless - Monitor - AccessPoint) or within the SSID settings (AccessControll)?

[CHGR]

I configured it for access point.

OK, got the same problem, when I set up google-dns in there, as well.

Our internal DNSs geht their time from 

ptbtime1.ptb.de /2/3 

When I use one of these 3 IPs it works. These IPs are allowed at our firewall, google-dns not. Maybe google-dns for NTP is blocked at yours as well.

Hello. Thank you for your advise.

However, these 3 ip addresses doesn't work.

I guess these are not allowed on our firewall.
