chez.jcz.fr has multiple IP addresses in its DNS records. While they appear to be accessible on the network, we have detected that they produce differing results when sent an ACME HTTP validation request. This may indicate that some of the IP addresses may unintentionally point to different servers, which would cause validation to fail.
