Test result for zab.ordana.net using http-01

A validation request to this domain resulted in an HTTP request being made to a port that expects to receive HTTPS requests. This could be the result of an incorrect redirect (such as to http://example.com:443/) or it could be the result of a webserver misconfiguration, such as trying to enable SSL on a port 80 virtualhost.

zab.ordana.net 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.
