Question

使用启用了SSL的RabbitMQ客户端时，CreateConnection();会抛出异常。

内部异常是SSPI，内部是令牌无效异常。

RabbitMQ服务器已在java中测试并按预期工作，因此问题必须出在.Net安全库中。

有谁知道怎么解决这个问题？

C＃代码：

    var factory = new ConnectionFactory();
    factory.HostName = "hostname";
    factory.Port = 5671;
    factory.UserName = "username";
    factory.Password = "password";
    factory.Ssl.Enabled = true;

    var conn = factory.CreateConnection();

例外：

我们遇到了同样的问题，需要花费数小时才能弄清楚发生了什么。它实际上并没有直接与.Net客户端有关，即使Java客户端工作让我们相信它。

我们的主要问题是由AWS上的Ubuntu映像附带的Erlang版本引起的。（Erlang R16B03）。我们更新到Erlang版本17.4，它开始工作了！：）
