Errors (2)
  • cz to rhybar.cz: 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. (217.31.57.6, 217.31.207.98, 217.31.207.99, 2001:1488:800:126::98, 2001:1488:800:126::99, 2001:1ab0:7e1e:d150::8:1, UDP_-_EDNS0_4096_D_KN)
  • cz to rhybar.cz: The DS RRset for the zone included algorithm 13 (ECDSAP256SHA256), but no DS RR matched a DNSKEY with algorithm 13 that signs the zone's DNSKEY RRset. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11. (217.31.57.6, 217.31.207.98, 217.31.207.99, 2001:1488:800:126::98, 2001:1488:800:126::99, 2001:1ab0:7e1e:d150::8:1, UDP_-_EDNS0_4096_D_KN)
