Errors (5)
  • gov to smokefree.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, 2607:f220:402:1801::a570:4e6, 2607:f220:404:101::80e7:80fb, 2607:f220:418:4101::80e7:401, TCP_-_EDNS0_4096_D_KN)
