. to ελ: 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. (78.104.145.227, 139.91.1.1, 139.91.191.3, 194.0.1.25, 194.0.4.10, 194.0.11.102, 2001:648:2c30::191:3, 2001:678:4::19, 2001:678:7::4:10, 2001:678:e:102::53, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_512_D_KN)
. to ελ: The DS RRset for the zone included algorithm 7 (RSASHA1NSEC3SHA1), but no DS RR matched a DNSKEY with algorithm 7 that signs the zone's DNSKEY RRset. (78.104.145.227, 139.91.1.1, 139.91.191.3, 194.0.1.25, 194.0.4.10, 194.0.11.102, 2001:648:2c30::191:3, 2001:678:4::19, 2001:678:7::4:10, 2001:678:e:102::53, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_512_D_KN)
ελ/DNSKEY: No response was received from the server over UDP (tried 4 times). (139.91.191.3, UDP_-_EDNS0_512_D_KN)
ελ/NS: No RRSIG covering the RRset was returned in the response. (78.104.145.227, 139.91.1.1, 139.91.191.3, 194.0.1.25, 194.0.4.10, 194.0.11.102, 2001:648:2c30::191:3, 2001:678:4::19, 2001:678:7::4:10, 2001:678:e:102::53, UDP_-_EDNS0_4096_D_KN)
ελ/SOA: No RRSIG covering the RRset was returned in the response. (78.104.145.227, 139.91.1.1, 139.91.191.3, 194.0.1.25, 194.0.4.10, 194.0.11.102, 2001:648:2c30::191:3, 2001:678:4::19, 2001:678:7::4:10, 2001:678:e:102::53, TCP_-_EDNS0_4096_D_N, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_4096_D_KN_0x20)

. to ελ: The following NS name(s) were found in the authoritative NS RRset, but not in the delegation NS RRset (i.e., in the . zone): gr-m.ics.forth.gr
ελ/DS (alg 7, id 55983): DNSSEC specification prohibits signing with DS records that use digest algorithm 1 (SHA-1).
ελ/DS (alg 7, id 55983): DNSSEC specification prohibits signing with DS records that use digest algorithm 1 (SHA-1).
ελ/DS (alg 7, id 55983): DS records with digest type 1 (SHA-1) are ignored when DS records with digest type 2 (SHA-256) exist in the same RRset.
ελ/DS (alg 7, id 55983): DS records with digest type 1 (SHA-1) are ignored when DS records with digest type 2 (SHA-256) exist in the same RRset.
ελ/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. (139.91.191.3, UDP_-_EDNS0_4096_D_KN)
