I'm trying out a new installation from scratch. The errors continued. I'll see what happens now
The issue with CloudFlare is not that it doesn't return any info. They don't support the outdated DNS_ANY, but they support DNS_ALL, which will return all the DNS records. However, changing that it won't work either because they do CNAME flattering, so they convert CNAME to A records.Seems your dns is hosted with cloudflare?
So the dns server does not return any info.
