私はJava 8を使用しており、SSLSocketでこのURLをリクエストしています: https://www.flixbus.de/sites/default/files/6_jetzt_buchen_button_tiny.png

いつもハンドシェイクエラーが発生します。特定のプロトコルの使用を強制する socket.setEnabledProtocols() は役に立ちませんでした。

ところで、他のすべての Web サーバーは正常に動作します。したがって、おそらく私のコードとは関係ありません。

このエラーは、ssl/tls プロトコルの制限なしでも発生します。

何か案は？

オプション「javax.net.debug=all」を使用した出力は次のとおりです。

このエラーは、サーバーが使用している Tls1.2 をサポートしていない可能性があります
