Comment (by cypherpunks):

 [https://codeberg.org/crimeflare/cloudflare-
 tor/src/branch/master/PEOPLE.md Like other online users], Cloudflare's DNS
 sometimes return their own internal IP address. This behaviour results in
 [https://codeberg.org/crimeflare/cloudflare-
 tor/media/branch/master/image/cferr1016.jpg DNS error screen].

 You better ask Tor exit owners to change their DNS server to ISP one, or
 run unbound locally.
