Errors (8)
  • ch to tcp53.ch: 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. (91.184.32.34, 178.33.39.66, 2001:41d0:304:200::c92a, 2a01:198:0:1::34, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_512_D_KN)
  • ch to tcp53.ch: 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. (91.184.32.34, 178.33.39.66, 2001:41d0:304:200::c92a, 2a01:198:0:1::34, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_512_D_KN)
