Errors (10)
  • gov to leo.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. (153.31.113.139, 153.31.192.139, 2607:f330:2003:403::201, TCP_-_EDNS0_4096_D_KN)
  • gov to leo.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. (153.31.113.139, 153.31.192.139, 2607:f330:2003:403::201, TCP_-_EDNS0_4096_D_KN)
