RedirectToAction在Azure中不起作用

这发生在我的MVC项目的登录屏幕上，控制器代码如下：

[HttpPost]
    [AllowAnonymous]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
    {
        if (!ModelState.IsValid)
        {
            return View(model);
        }

        var result = await SignInManager.PasswordSignInAsync(model.UserId, model.Password, model.RememberMe, shouldLockout: false);
        switch (result)
        {
            case SignInStatus.Success:
                return RedirectToAction("Index", "Home"); <-- Gets here OK
            case SignInStatus.LockedOut:
                return View("Lockout");
            case SignInStatus.RequiresVerification:
                return RedirectToAction("SendCode", new { ReturnUrl = returnUrl, RememberMe = model.RememberMe });
            default:
                ModelState.AddModelError("", "Login details were incorrect.");
                return View(model);
        }
    }

获取操作确定，成功登录后转到RedirectToAction，然后返回登录屏幕 .

如果我通过localhost在本地运行它，它可以正常工作，点击Home Controller上的Index操作的断点 . 从Azure调试时，它没有 .

登录视图是：

@using (Html.BeginForm("Login", "Account", new { ReturnUrl = ViewBag.ReturnUrl }, FormMethod.Post, new { @class = "form-horizontal", role = "form" })) {
            @Html.AntiForgeryToken()
            <h3 class="form-title">Sign In to your Account</h3>
            <hr />
            @Html.ValidationSummary(true, "", new { @class = "text-danger" })
            <div class="form-group">
                <!--@Html.LabelFor(m => m.UserId, new {@class = "col-md-2 control-label"})-->
                <div class="input-icon">
                    <i class="icon-user"></i>
                    @Html.TextBoxFor(m => m.UserId, new { @class = "form-control", @placeholder = "Username" })
                    @Html.ValidationMessageFor(m => m.UserId, "", new { @class = "text-danger" })
                </div>
            </div>
            <div class="form-group">
                <!--@Html.LabelFor(m => m.Password, new {@class = "col-md-2 control-label"})-->
                <div class="input-icon">
                    <i class="icon-lock"></i>
                    @Html.PasswordFor(m => m.Password, new { @class = "form-control", @placeholder = "Password" })
                    @Html.ValidationMessageFor(m => m.Password, "", new { @class = "text-danger" })
                </div>
            </div>

            <div class="form-actions">
                <div class="checkbox pull-left">
                    @Html.CheckBoxFor(m => m.RememberMe, htmlAttributes: new { @class = "uniform checkbox" })
                    @Html.LabelFor(m => m.RememberMe, htmlAttributes: new { @class = "control-label" })
                </div>
                <button type="submit" class="submit btn btn-primary pull-right">
                    Sign In <i class="icon-angle-right"></i>
                </button>
            </div>
        }

主页/索引是一个令人兴奋的：

public ActionResult Index() {
        return View();
    }

不确定这是我的代码，还是需要在Azure中设置？
