Errors (6)
  • gov.tw to ly.gov.tw: No valid RRSIGs made by a key corresponding to a DS RR were found covering the DNSKEY RRset, resulting in no secure entry point (SEP) into the zone. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11. (210.69.138.121, 210.69.138.122, 210.241.74.121, 210.241.74.122, 2001:4420:601b:2::ac8:c079, 2001:4420:601b:2::ac8:c07a, 2001:4420:601c:2::c0a8:179, 2001:4420:601c:2::c0a8:17a, UDP_-_EDNS0_4096_D_KN)
