tn/DNSKEY: No response was received from the server over UDP (tried 4 times). See RFC 1035, Sec. 4.2. (2c0f:fab0:ffff:4:41:228:62:63, UDP_-_EDNS0_512_D_KN)
tn/SOA: DNSSEC was effectively downgraded because no response was received from the server over UDP (tried 10 times) with the DO bit set. See RFC 4035, Sec. 3.2.1. (2c0f:fab0:ffff:4:41:228:62:63, UDP_-_EDNS0_4096_)
tn/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). See RFC 6891, Sec. 6.1.4. (2c0f:fab0:ffff:4:41:228:62:63, UDP_-_EDNS0_4096_D_KN)
tn/SOA: The DNSSEC records necessary to validate the response could not be retrieved from the server. See RFC 4035, Sec. 3.1.1, RFC 4035, Sec. 3.1.3. (2c0f:fab0:ffff:4:41:228:62:63, UDP_-_EDNS0_4096_D_KN)
tn/DNSKEY has errors; select the "Denial of existence" DNSSEC option to see them.

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. See RFC 6891, Sec. 6.2.6. (2c0f:fab0:ffff:4:41:228:62:63, UDP_-_EDNS0_4096_D_KN)
