Check This Out I found that while using the affected cert type listed above, my server only supported TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA and TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA, clearly a very limited subset. Fire up the tool on either the client or server with the proper capture filters to reduce noise, and then attempt the failing connection.
