_MST2_ what kind of DNS provider is that ?
It was under the impression that the DNS specification does not permit to have a CNAME record at the root if there is another record, as as there is always an NS record this not possible.
However I notice the FreeFlarum docs say otherwise https://www.freeflarum.com/docs/howto/custom-domain/#using-a-root-naked-domain According to these it could work.
As matteocontrini pointed out, you can try querying the domain yourself, it doesn't return any A or CNAME record. I have the same results.
The best would be to contact your hosting provider to see whether they really support adding a CNAME at the root, or not use the root domain and go for a subdomain instead.
