  • dev to tomservo.dev: 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. (173.245.58.51, 173.245.59.41, 198.41.222.173, 2400:cb00:2049:1::adf5:3a33, 2400:cb00:2049:1::adf5:3b29, 2400:cb00:2049:1::c629:dead, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_512_D_KN)
