Errors (8)
  • gov to gpodev.gov: 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. (162.140.15.100, 162.140.254.200, UDP_-_EDNS0_4096_D_KN)
  • gov to gpodev.gov: The DS RRset for the zone included algorithm 8 (RSASHA256), but no DS RR matched a DNSKEY with algorithm 8 that signs the zone's DNSKEY RRset. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11. (162.140.15.100, 162.140.254.200, UDP_-_EDNS0_4096_D_KN)
