C# 用于登录的LTPA令牌无效-Maximo Rest API

我正在构建一个访问Maximo Rest API的应用程序，我使用这段代码调用API

我正在使用.NETFramework4.5C#

正如您所看到的，我正在使用cookie容器捕获在进行身份验证时随响应发送的cookie。Authenticate（）有效。它返回一个302，带有一个LTPA令牌。但是GET请求失败。我得到这个错误：

用于登录的LTPA令牌无效。启用WebSphere Application Server安全性时，LTPA令牌用于登录过程。请等待几秒钟，然后再次尝试登录。如果问题仍然存在，请清除浏览器cookie或重新启动浏览器

当我使用Postman时，我会遇到类似的错误，但当我再次尝试请求时，它会起作用

我交换了框架，使用了.NETCore2.1。完全相同的代码没有任何问题

为什么这适用于.NETCore而不是.NETFramework？使用.NETCore并不能解决我的问题，它必须是.NET4.5。有人能帮我解决这个问题吗？

这不是答案，但是，实现重试调用可以解决这个问题。我仍然想知道为什么这是必要的。
