Nuget Server Repository - Page not found 404

Question

I'm totally desperate. I've been trying to install Nuget.Server v3.2.1.0 for two days now. I followed the installation instructions at https://learn.microsoft.com/de-de/nuget/hosting-packages/nuget-server, but it doesn't work.

I suspect that the routing doesn't work properly.

My Web.config looks like:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.web>
    <compilation strict="false" explicit="true" debug="true" targetFramework="4.6" />

    <!-- maxRequestLength is specified in Kb -->

  </system.web>

</configuration>

And here is my development environment: - Visual Studio 2017 Pro (15.9.12) - Windows 10 Enterprise LTSC - IIS Express 10.0 (Visual Studio integrated)

The installation is very simple. The overview page is also displayed:

What I find confusing is that the Default.aspx file contains the following:

Click <a href="<%= VirtualPathUtility.ToAbsolute("~/nuget/Packages") %>">here</a> to view your packages.

And in the file NuGetODataConfig.cs the following is configured:

NuGetV2WebApiEnabler.UseNuGetV2WebApiFeed(
    config,
    "NuGetDefault,
    "nuget"
    "PackagesOData,
    enableLegacyPushRoute: true);

Anyway, when I click on "Click here to view your packages", I get the error: "Page not found - 404".

Does anyone have an idea why that might be? I am at the end of my Latin.

Many greetings

Update

I forgot to mention that I also tried to release the project on a Windows Server 2012 R2. Exactly the same problem.

And it's strange that you can find the following packages in my project references: - Nuget.Core - Nuget.server - Nuget.Server.Core - Nuget.Server.V2

Then why does the start page talk about Nuget.Server 3.2.1.0?
