I have a domain on my hoster who is root to CloudFlare (my hoster has chaneg NameServer to Cloudlfare) and it works good.
I have create a sub-domain on this domain.
I have create a new record “A” type for this sub-domain on CloudFlare.
=> I have a 522 error
It’s not a problem of IP whitelist because my hoster doesn’t block IP.
I don’t understand…
