[電子發票] 電子發票串接財政部回復錯誤訊息:javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

此錯誤訊息為財政部需要回傳資料到return url.發現憑證與domain不match或是handsharking不過造成.

解決方式:
                調整Apache Web server 設定 SSL的protocols及Cipher Suite.
             
                到https://www.ssllabs.com/ssltest/測試調整結果.

                Java 6u45  至少要可以handshake通過
