I have:
C:\Windows\System32>nslookup flightproxy-euno-02-teams.cloudapp.net
Server: family-filter-dns.cleanbrowsing.org
Address: 185.228.168.168
Non-authoritative answer:
Nome: flightproxy-euno-02-teams.cloudapp.net
Address: 52.114.76.109
Why the server is Cleanbrowsing? I have Cloudflare in the internet setting and Quad9 in the access Control. This is very strange.
I have only Cleanbrowsing as DNS on Windows, but i know that Access Control override it.
Anyway I don’t think this is the problem, why there is no reason Cleanbrowsing should block cloudapp.
