zorbas-tegernsee.bayern has both AAAA (IPv6) and A (IPv4) records. While they both 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 the IPv4 and IPv6 addresses may unintentionally point to different servers, which would cause validation to fail.
[Address Type=IPv4,Server=Apache,HTTP Status=301,Number of Redirects=1,Final HTTP Status=300] vs [Address Type=IPv6,Server=Apache,HTTP Status=300]
