Errors (7)
  • gov to frtr.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. (134.67.12.5, 134.67.12.15, 161.80.212.5, 161.80.212.15, 2620:117:506f:c::f005, 2620:117:506f:c::f00f, 2620:117:5071:d4::f005, 2620:117:5071:d4::f00f, UDP_-_EDNS0_4096_D_KN)
