Errors (10)
  • . to ελ: 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. (78.104.145.227, 194.0.1.25, 194.0.11.102, 2001:678:4::19, 2001:678:e:102::53, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_512_D_KN)
  • . to ελ: 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. (78.104.145.227, 194.0.1.25, 194.0.11.102, 2001:678:4::19, 2001:678:e:102::53, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_512_D_KN)
