DNS request timed out (Again)

busthead

I've read other users posts who have experienced the dreaded "DNS request timed out" error and also DNS best practice and Rulz but still have no idea what causes this:

C:\Windows\system32>nslookup api.netatmo.com
DNS request timed out.
    timeout was 2 seconds.
Server:  UnKnown
Address:  192.168.0.1

DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
Non-authoritative answer:
DNS request timed out.
    timeout was 2 seconds.
Name:    front-azure.netatmo.net
Address:  51.145.143.28
Aliases:  api.netatmo.com

192.168.0.0/24 has been added to DNS-Global-Allowed Networks

DNS-Forwarders have been configured with an Availability group containing Cloudflare Gateway DNS servers and 'Use forwarders assigned by ISP' is unchecked

DNS-Request Routing is empty. I'm not doing any reverse DNS for internal IPs

QoS is disabled for all networks

If I specify one of the Cloudflare DNS servers on the same host, instead of the UTM as the DNS server, no DNS time outs occur.

Here are some DNS logs:

What am I not understanding?
