Errors (11)
  • . to club: 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. (156.154.145.215, 156.154.156.215, 156.154.157.215, UDP_-_NOEDNS_)
  • . to club: 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. (156.154.145.215, 156.154.156.215, 156.154.157.215, UDP_-_NOEDNS_)
  • club/DNSKEY (alg 8, id 29815): DNSSEC was effectively downgraded because the response had an invalid RCODE (SERVFAIL) with EDNS enabled. See RFC 6891, Sec. 7, RFC 2671, Sec. 5.3. (156.154.145.215, 156.154.156.215, 156.154.157.215, UDP_-_NOEDNS_)

  • club/DNSKEY (alg 8, id 29815): The response had an invalid RCODE (SERVFAIL) until EDNS was disabled (however, this server appeared to respond legitimately to other queries with EDNS enabled). See RFC 6891, Sec. 6.2.6. (156.154.145.215, 156.154.156.215, 156.154.157.215, UDP_-_EDNS0_4096_D_KN)
