我有用于安全 websocket 连接的 spring-boot Tomcat 服务器。服务器接受 Android 4.4、iOS、Firefox 和 Chrome 客户端而不会失败，并带有授权签名的证书。但是，Android 5.0 无法通过 SSL 握手。

我认为问题在于 TLS 或密码套件，因为Android 5.0 Lollipop 发生了变化，而不是证书，因为其他客户端连接，但我不知道如何判断连接的客户端发生了什么，因为SSL Android 似乎不支持调试。该问题可能与此问题非常相似，该问题也尚未解决，但表明问题出在密码套件上。Android 错误88313 81603 developer-preview-1989似乎表明 Android 实现是正确的，但服务器配置或密码套件的实现可能不正确。
我设置了以下服务器密码套件
server.ssl.ciphers = TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_128_CBC_SHA,TLS_DHE_RSA_WITH_AES_128_CBC_SHA,TLS_DHE_DSS_WITH_AES_128_CBC_SHA
特别是，TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA 在适用于 API 11+的 Android 支持的协议列表中。
我验证了服务器支持这个
openssl s_client -connect server:port
返回
SSL-Session:
Protocol : TLSv1.2
Cipher : ECDHE-RSA-AES128-SHA
openssl 和 java 之间的名称略有不匹配，但openssl 文档说它们是相同的密码套件。
我的服务器首先支持并与与 Android 5.0 兼容的 openssl 客户端协商一个密码套件。我希望 Android 5.0 可以毫无问题地连接，但它失败了。
有没有人成功地将 Android 5.0 安全 websocket 连接连接到 Tomcat？是否有已知可以工作的密码套件？有没有办法调试 Android 客户端 SSL 实现？

当 Android 5.0 设备（Nexus 5）接收到以 4-5 个数据包发送的服务器证书信息时，它会以可变数量 (2-4) 的 ACK 响应，然后是 FIN、ACK。在成功的跟踪中，客户端不发送 FIN。Android 5 客户端不喜欢它从服务器获得的东西。
对于失败，服务器 SSL 调试信息说：
