Errors (4)
  • gov.gr/SOA: DNSSEC was effectively downgraded because no response was received from the server over UDP (tried 10 times) with the DO bit set. (2001:648:2c30::191:3, UDP_-_EDNS0_4096_, UDP_-_EDNS0_4096__0x20)
  • gov.gr/SOA: No response was received from the server over UDP (tried 10 times) until the DO EDNS flag was cleared (however, this server appeared to respond legitimately to other queries with the DO EDNS flag set). (2001:648:2c30::191:3, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_4096_D_KN_0x20)
  • gov.gr/SOA: The DNSSEC records necessary to validate the response could not be retrieved from the server. (2001:648:2c30::191:3, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_4096_D_KN_0x20)
  • gr/DNSKEY: No response was received from the server over UDP (tried 4 times). (2001:648:2c30::191:3, UDP_-_EDNS0_512_D_KN)
