Errors (4)
  • libhydrogen.org/DNSKEY: No response was received from the server over UDP (tried 4 times). (82.64.197.71, UDP_-_EDNS0_512_D_K)
  • libhydrogen.org/MX: No response was received from the server over UDP (tried 4 times). (82.64.197.71, UDP_-_EDNS0_512_D_K)
  • org to libhydrogen.org: 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. (37.59.238.213, 82.64.197.71, UDP_-_EDNS0_4096_D_K, UDP_-_EDNS0_512_D_K)
  • org to libhydrogen.org: 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. (37.59.238.213, 82.64.197.71, UDP_-_EDNS0_4096_D_K, UDP_-_EDNS0_512_D_K)
Warnings (1)
  • libhydrogen.org/SOA: No response was received until the UDP payload size was decreased, indicating that the server might be attempting to send a payload that exceeds the path maximum transmission unit (PMTU) size. (82.64.197.71, UDP_-_EDNS0_4096_D_K_0x20)
