Answer 1

I found an HTTPS server which failed in this way if my Java client process was configured with

-Djsse.enableSNIExtension=false

The connection failed with handshake_failure after the ServerHello had finished successfully but before the data stream started.

There was no clear error message that identified the problem, the error just looked like

main, READ: TLSv1.2 Alert, length = 2
main, RECV TLSv1.2 ALERT:  fatal, handshake_failure
%% Invalidated:  [Session-3, TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384]
main, called closeSocket()

I isolated the issue by trying with and without the "-Djsse.enableSNIExtension=false" option
