TLS 1.1/1.2 detection issue in SSL Server Test

Host in question is (, port 443, should be up.

SSL Server Test shows that neither TLS 1.1 nor TLS 1.2 are supported there, which seem to be incorrect.


nginx (1.4.5, openssl 1.0.1g) there is configured with "ssl_protocols TLSv1.2 TLSv1.1 TLSv1;", but is sitting behind haproxy (tcp mode with "tcp-request inspect-delay 2s", not terminating tls) that probably delays connections a little bit.

"openssl s_client -tls1_2 -connect" and browsers (e.g. FF 31.0a2) can (and do) use TLS 1.2 there, which I've also confirmed in pcap dumps.


So the test results seem to be unexpected and seem to offer no explaination as to why that's a solid "No" with the protocols actually enabled and used by other tools.

If it's indeed a valid result (i.e. 1.2 is enabled, but somehow broken), maybe more visible explaination or third alternative to binary "Yes/No" would help.


Thanks for the nice tool/service.
