Meraki blocking Google DNS?

Hi Everyone

 

This morning I've had users complain about slow / no internet. Upon reviewing the event log I am seeing that Google DNS has been categorised by Meraki as proxy avoidance. Is anyone else having issues?

Isn't that :443 (and not :53) the newish Chrome secure DNS thing? I know it has been problematic for various reasons and this appears to be another..

 

I'll check some of my orgs to see if I am getting the same, but have not had any trouble tickets or noticed it yet.

Disable DNS over HTTPS in Chrome.

Getting noticed

We're getting this and DNS over HTTPS is disabled.   How can I see more detail on these events?  It's causing so many that some events aren't even being logged.

On the Network template if you navigate to Security & Sd-wan. Then select Content filtering type https://dns.google/ in the URL box at the top and check. It will show you DoH and DoT are blocked under Category blocking. 

 

Adding in case anyone else has the issue
