尝试使用 Identity.UserManager 确认电子邮件时出错

Question

我正在使用 SendGrid API 发送验证电子邮件。它在 SendGrid 和 Azure 上运行良好，我的应用程序之前托管在 Azure 上。但是，部署到 IIS 服务器后，在我的 VPS 上，当我尝试确认从 SendGrid 返回的用户电子邮件时，出现错误：

var result = await _userManager.ConfirmEmailAsync(user, token);

从事件查看器日志中，警告是：

Category: Microsoft.AspNetCore.Identity.UserManager
EventId: 9
SpanId: 3830373dac59b144
TraceId: 2654243922e29b43b4ade992e096d1d3

ActionId: 65237a3f-acf5-4dda-93d6-c37a34f1a351
ActionName: Kepler.MVC.Areas.Identity.Controllers.AccountController.EmailConfirmation (Kepler.MVC)

VerifyUserTokenAsync() failed with purpose: EmailConfirmation for user.

上面的错误是关于令牌验证吗？为什么会发生？

除此之外，抛出错误异常，事件查看器日志上的错误是：

我注意到 Error.cshtml 的路径指向我的本地主机 C:\Users\gutox\source epos\Gutobarroso\GooGit\Kepler.MVC\Views\Shared\Error.cshtml:第 9 行

但是我已经完成了部署到 IIS 服务器托管。我不再使用本地主机了。如何/在哪里可以更改它？

我正在使用 .NET 5、IIS 10。

我的错。我在回调 url 令牌的末尾传递了一个单引号。所以，比较时，代币是不同的。
