cz to szn-broken-dnssec.cz: 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. (77.75.74.80, 77.75.75.230, 2a02:598:3333::3, 2a02:598:4444::4, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_512_D_KN)
cz to szn-broken-dnssec.cz: The DS RRset for the zone included algorithm 13 (ECDSAP256SHA256), but no DS RR matched a DNSKEY with algorithm 13 that signs the zone's DNSKEY RRset. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11. (77.75.74.80, 77.75.75.230, 2a02:598:3333::3, 2a02:598:4444::4, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_512_D_KN)
szn-broken-dnssec.cz/CDNSKEY: The CDNSKEY RRset must be signed with a key that is represented in both the current DNSKEY and the current DS RRset. See RFC 7344, Sec. 4.1.
szn-broken-dnssec.cz/CDS: The CDS RRset must be signed with a key that is represented in both the current DNSKEY and the current DS RRset. See RFC 7344, Sec. 4.1.
