tfs - 团队基础服务器 : HTTP code 400 - Bad Request

Question

Team Foundation Server 有问题。 “HTTP code 400: Bad Request”错误消息出现在 Visual Studio 中的不同位置(请参阅带屏幕截图的附件)(例如，在单击“待定更改”、“源代码管理资源管理器”、“获取最新版本”等之后... ).

我们公司有 3 名开发人员。错误消息是随机的，有时它可以工作，然后错误消息出现...或者错误消息仅出现在计算机 1 和计算机 2 上。第三台计算机正常。第二天，开发者1正常，另外两个出现错误信息...

我们的环境:

客户:3 台 PC，Visual Studio Professional 2015，Windows 10

TFS 服务器:Win2012 R2、TFS 2015 Update 3

SQL 服务器:SQL 2012 标准

Answer 1

要缩小问题范围，您可以尝试重置 IIS 服务器。如果您使用任何代理，请尝试删除代理并重试。还要查看TFS服务器上的事件 View ，看是否有相关信息可以解决问题。

根据您的错误截图和错误 ID TF400813。下次当你无法通过 VS 连接到 TFS 时，你可以试试这个:

1. 在 Visual Studio 的右上角，您会发现一个彩色的盒子里面有你的名字或你的首字母缩写。单击向下箭头，然后然后是账户设置。在打开的窗口中，请点击“签名out"在窗口的左上部分。
2. 重新启动 Visual Studio 并重新登录后，错误应该走了。
