Hi,

i Have a infrastructure with 7 AP Meraki ( six MR74 and one MR33) , but for a month ,i have a problem with yellow alert "DNS is misconfigured". 

All AP is configured with IP Static with dns primary 1.1.1.1 and dns secondary 8.8.4.4.

All AP can navigated on internet without problem.

How can i delete this problem/alert?

Thanks

You can't delete it, however you can fix it. Something down the line is blocking DNS by the looks of it. Are you able to test it from the TOOLS page on one of the AP's, try to resolve a URL name etc.

You must have a firewall blocking some services, you should be able to ping that IP address and also names, like below:

yes, probably the problem is on the cisco asa firewall.

After emergency in italy, I will go directly to the field to check and I will update the topic.

Thanks for your help.
