Errors (6)
  • tn zone: The server(s) were not responsive to queries over TCP. (147.28.0.39, 192.93.0.4)
  • tn/SOA: DNSSEC was effectively downgraded because no response was received from the server over UDP (tried 11 times) with EDNS enabled. (2c0f:fab0:ffff:5:41:228:63:62, UDP_-_NOEDNS_)
  • tn/SOA: No response was received from the server over TCP (tried 3 times). (192.93.0.4, TCP_-_EDNS0_4096_D_N)
  • tn/SOA: No response was received from the server over TCP (tried 4 times). (147.28.0.39, TCP_-_EDNS0_4096_D_N)
  • tn/SOA: No response was received from the server over UDP (tried 11 times) until EDNS was disabled (however, this server appeared to respond legitimately to other queries with EDNS enabled). (2c0f:fab0:ffff:5:41:228:63:62, UDP_-_EDNS0_4096_D_KN)
  • tn/SOA: The DNSSEC records necessary to validate the response could not be retrieved from the server. (2c0f:fab0:ffff:5:41:228:63:62, UDP_-_EDNS0_4096_D_KN)
Warnings (1)
  • tn/NS: 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. (2c0f:fab0:ffff:5:41:228:63:62, UDP_-_EDNS0_4096_D_KN)
