Question

当尝试从Windows计算机上运行的应用程序连接到Neo4j服务器时，我们收到以下错误消息：

Neo4j.Driver.V1.SecurityException：无法建立加密与服务器bolt：// neo4jserver：7687 /连接。 ---> System.Security.Authentication.AuthenticationException：对SSPI的调用失败，请参阅内部异常。 ---> System.ComponentModel.Win32Exception：提供给该函数的令牌无效

Neo4j浏览器工作正常，只有从应用程序到Neo4j的连接失败。这是完整的调用堆栈：

Neo4j.Driver.V1.SecurityException: Failed to establish encrypted connection with server bolt://neo4jserver:7687/. 
---> System.Security.Authentication.AuthenticationException: A call to SSPI failed, see inner exception. 
---> System.ComponentModel.Win32Exception: The token supplied to the function is invalid

在客户端计算机上安装所有Windows更新程序即可解决此问题。

事实证明，Neo4j要求客户端在连接时使用TLS 1.2，但是并非所有Windows版本默认都支持它。

可能不需要所有更新，但这是最简单的方法。
