Errors (9)
  • brain.gov/CDNSKEY: No response was received from the server over UDP (tried 12 times). See RFC 1035, Sec. 4.2. (128.231.64.1, 128.231.128.251, 165.112.4.230, UDP_-_NOEDNS_)
  • brain.gov/CDS: No response was received from the server over UDP (tried 12 times). See RFC 1035, Sec. 4.2. (128.231.64.1, 128.231.128.251, 165.112.4.230, UDP_-_NOEDNS_)
  • gov to brain.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. (128.231.64.1, 128.231.128.251, 165.112.4.230, TCP_-_EDNS0_4096_D_KN)
  • gov to brain.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. (128.231.64.1, 128.231.128.251, 165.112.4.230, TCP_-_EDNS0_4096_D_KN)
