You may get this error when trying to browse an ASP.NET application.
The debug information shows that «This error can be caused by a virtual directory not being configured as an application in IIS.»
However, this error occurs primarily out of two scenarios.
- When you create an new web application using Visual Studio .NET, it automatically creates the virtual directory and configures it as an application. However, if you manually create the virtual directory and it is not configured as an application, then you will not be able to browse the application and may get the above error. The debug information you get as mentioned above, is applicable to this scenario.
To resolve it, right click on the virtual directory — select properties and then click on
«Create» next to the «Application» Label and the text box. It will automatically create the «application» using the virtual directory’s name. Now the application can be accessed.
- When you have sub-directories in your application, you can have web.config file for the sub-directory. However, there are certain properties which cannot be set in the
web.configof the sub-directory such as authentication, session state (you may see that the error message shows the line number where the authentication or session state is declared in the web.config of the sub-directory). The reason is, these settings cannot be overridden at the sub-directory level unless the sub-directory is also configured as an application (as mentioned in the above point).
Mostly, we have the practice of adding web.config in the sub-directory if we want to protect access to the sub-directory files (say, the directory is admin and we wish to protect the admin pages from unauthorized users).

I had this error when the .NET version was wrong — make sure the site is configured to the one you need.
See aspnet_regiis.exe for details.

It sounds like the admin has locked the «authentication» node of the web.config, which one can do in the global web.config pretty easily. Or, in a nutshell, this is working as designed.

I just had the same issue on visual studio 2012. For a internet application project.
How to resolve “Server Error in ‘/’ Application” error?
Searching for answer I came across this post, but none of these answer help me.
Than I found another post here on stackoverflow that has the answer for resolving this issue.

I also got this error when I moved an entity framework edmx file into a «Models» sub-folder. This automatically changed the metadata in my connection string setting in my app.config.
So before the connection string changed… it looked something like this:
<connectionStrings>
<add name="MyDbEntities" connectionString="metadata=res://*/MyDb.csdl|res://*/MyDb.ssdl|res://*/MyDb.msl; ...
</connectionStrings>
And after… it added the «Models» subfolder name (btw… it also added «Models» to the namespace for the EF classes generated) and the connection string now looks something like this:
<connectionStrings>
<add name="MyDbEntities" connectionString="metadata=res://*/Models.MyDb.csdl|res://*/Models.MyDb.ssdl|res://*/Models.MyDb.msl; ...
</connectionStrings>
I have a website project that references this Entity Framework DB project. But its web.config did not have the updates to the connection string… and that’s when I started getting the compilation error being discussed here.
To fix this error, I updated the connection string in the web.config in the website project to match the app.config in my EntityFramework project.

I opened the Properties window for the website project in question and changed Windows Authentication to «Enabled» and that resolved my issue in VS 2019.

The error message is quite clear: you have a configuration element in a web.config file in a subfolder of your web app that is not allowed at that level — OR you forgot to configure your web application as IIS application.
Example: you try to override application level settings like forms authentication parameters in a web.config in a subfolder of your application

You need to create an application in IIS for you website that points to the root directory of the site as it is deployed on the server. You will also need to create an Application Pool that is set to .Net Framework 4 to manage the IIS process that your site will run as.
You’re getting the error because the default website in IIS (usually set to c:inetpubwwwroot) doesn’t know anything about the pages within your website.

There are various reasons for why you may encounter a “Server error in ‘/’ application”. Often the error message provides a bit more detail of what’s wrong. In most cases, the server-side error message is related to IIS (Internet Information Services) or ASP.NET.
Requirements
- Cloud Server running Windows Server 2012
- ASP.NET installed
vServer (VPS) from IONOS
Low-cost, powerful VPS hosting for running your custom applications, with a personal assistant and 24/7 support.
100 % SSD storage
Ready in 55 sec.
SSL certificate
Restart IIS
The “Server error in ‘/’ application” can happen if IIS needs to be restarted. You can restart IIS from the IIS Manager. From your Remote Desktop connection, click the “Start” button in the lower left-hand corner and select “Administrative Tools”.
Click “Internet Information Services (IIS) Manager” to launch the IIS manager.
Select the affected server from the left-hand panel.
On the right of the IIS Manager, click “Restart” to restart IIS.
Update the URL
Under some circumstances, a 404 error may be displayed as “Server error in ‘/’ application”. When this is the case, the error description in the browser will clarify that the error has occurred because the file is missing or has been renamed.
To fix this problem, correct the URL in the link that triggers this error.
Cloud backup from IONOS
Make costly downtime a thing of the past and back up your business the easy way!
Add the MIME type
If you are accessing a file with a file extension that does not have permissions to be run on the server, you will see the “Server error in ‘/’ application” along with the explanation that “This type of page is not served”.
When exploring a solution to a “Server error in ‘/’ application”, first ensure that you are using the correct file name. The “Server error in ‘/’ application” can occur if there is a typo in the file extension, for example a file or URL that references test.htl instead of test.html.
If the file name is correct, then you may need to add the MIME type to the server. MIME stands for Multipurpose Internet Mail Extensions. The MIME type is used to indicate what type of document it is. In the example, we are trying to run a file called HelloWorld.cshtml. The file extension .cshtml is not associated with any MIME type by default on Windows 2012.
You can add the MIME type in the IIS Manager. To open the IIS Manager, from your Remote Desktop connection, click the Start button in the lower left-hand corner and “Administrative Tools”.
Click “Internet Information Services (IIS) Manager” to launch the IIS manager.
Click the server in the left-hand panel.
Now click “Sites”.
Then click on your domain. In the central panel, double-click “MIME Types”.
Under the “Actions” column on the right, click “Add”.
In the pop-up window which appears, fill in the “File name extension” and “MIME Type” fields, then click “OK”.
Note
You may need to do an Internet search to find the correct MIME Type for your file extension.
Verify the .NET Version
Some programs, features, and file types will only run under certain versions of .NET.
You can also check your .NET version from the IIS Manager. To open the IIS Manager from your Remote Desktop connection, click the “Start” button in the lower left-hand corner and then select “Administrative Tools”.
Click “Internet Information Services (IIS) Manager” to launch the IIS manager.
Click to expand the server in the left-hand window panel.
Click on “Application Pools”.
Right-click on the Domain Name and click on “Basic Settings”.
In the pop-up window which appears, select the .NET version from the drop-down menu, then click “OK” to confirm your choice.

The server error in ‘/’ application can occur when your programs and file types are not compatible with your .NET Version. This prevents your website from running on the Server.
Fortunately, the IIS Manager lets you check the version of .NET you are using, and this is crucial to resolving this issue. This isn’t the only issue that you can encounter, and many reported Internal server error 500 as well.
In this article, we will discuss the methods and steps we can use to fix the server In ‘/’ application error for good.
What does server error in application mean?
This is a server side issue that prevents the web app from running properly. The problem is associated with ISS and ASP.NET.
If there’s an issue with these components, you won’t be able to run the select app and it will crash while giving you this error.
What causes runtime error?
The problem is caused by missing resources or if you try to run a file with an extension that isn’t approved.
Another cause for this issue are the compatibility problems with .NET Framework.
How do I fix server error in ‘/’ application runtime error?
1. Try a different browser
If you notice that this error appears on your default browser, then maybe it would be the time that you install another one just to see if it reacts differently, and we suggest you try out Opera.
It is a very responsive browser that can load pages fast. Being often updated to meet the latest standards, if you don’t have any underlying issues with your .NET framework or drivers, you won’t have this error in Opera.
Opera is a Chromium-based web browser that is designed to be fast, lightweight, and still powerful. More so, it can be heavily customized using the wide variety of extensions that you have at your disposal in your digital library.
Some PC issues are hard to tackle, especially when it comes to corrupted repositories or missing Windows files. If you are having troubles fixing an error, your system may be partially broken.
We recommend installing Restoro, a tool that will scan your machine and identify what the fault is.
Click here to download and start repairing.
If you can load the page in Opera, then you may be better off setting it as your default browser. All of its components are of the latest version at all times, so errors such as the one described above are less likely to occur.
Opera
Browse the web with a lighter browser that keeps up with the latest security and performance needs!
2. Check the URL
If the problem still appears, check the URL. Sometimes a bad URL can lead to this issue, so be sure to check if it’s correct.
After updating the URL, the issue should be gone. If the problem persists, move to the next solution.
URL problems can cause Server error in ‘/’ application runtime error to appear in Safari, Chrome or other browser, but this should help you fix it.
3. Restart IIS using a graphical user interface
- Click the start windows button at the lower-left corner of your Desktop.
- Search for Administrative Tools and click on the result.
- Next, click on Internet Information Services (IIS) Manager to perform a restart when it opens.
- On the left pane, right-click on the server node and select All Tasks and then Restart IIS.
- Choose whether to restart IIS, stop IIS, start IIS, or reboot the Server and click OK.
- To restart an individual web or FTP site, right-click on the node for the site and select Stop, then repeat and select Start.
This method might help you fix Server error in ‘/’ application runtime error in Azure web app, so be sure to try it out.
4. Adding MIME Type to resolve server error in ‘/’ application.
- Search for the Administrative Tools on the Windows Start menu.
- Click on the Administrative Tools icon which will come on the search result.
- When Administrative Tools window displays, select Internet Information Services (IIS) Manager.
- Next, look on the left-hand pane, and select the Server.
- Click on Sites.
- Now, select your domain located in the central pane.
- Double-click MIME Types.
- Click Add Under the Actions column by the right.
- Fill in the File name extension and MIME Type fields In the pop-up window that will display.
- Confirm by clicking OK, then check to see if you are still getting the server error in ‘/’ application message.
You might need to run an Internet search so you can find the exact MIME type that will work with your file extension.
After making these changes, Server error in ‘/pods’ application will be gone.

Vista HB поставил в компонентах IIS в оснастке iis не появился, доступ 127.0.0.1 показывает ошибку
Ошибка сервера в приложении «Default Web Site»
HTTP Error 404.4 — Not Found
Описание: Ресурсу, который вы ищете, не сопоставлен обработчик.
Код ошибки: 0x80070002
Уведомление: MapRequestHandler
Модуль: IIS Web Core
Запрашиваемый URL-адрес: http://127.0.0.1:80/
Физический путь: C:inetpubwwwroot
Вход пользователя: Анонимная
Способ входа: Анонимная
Обработчик: Пока не определено
Наиболее вероятные причины:
- Расширение файла для запрашиваемого URL-адреса не имеет обработчика, сконфигурированного для обработки запроса на веб-сервере.
Что можно предпринять:
- Если расширение файла не имеет сопоставленного ему обработчика, добавьте сопоставление обработчика для данного расширения.
- Удостоверьтесь в том, что сопоставленный расширению файла обработчик должным образом установлен и сконфигурирован.
- Создайте правило трассировки, чтобы отслеживать невыполненные запросы для этого кода состояния HTTP. Чтобы получить дополнительные сведения о создании правила трассировки для невыполненных запросов, щелкните здесь.
Дополнительные сведения… Эта ошибка означает, что веб-сервер не распознает расширение файла запрашиваемого ресурса. Модуль обработки на данном веб-сервере не настроен для работы с этим расширением. Если отвергаемое расширение файла требуется веб-серверу, добавьте к расширению файла соответствующий обработчик.
Как этот обработчик установить?

Проблема в HB, она не поддерживает IIS как веб сервер. Все что там есть — поддержка WCF через HTTP. Для IIS требуется по меньшей мере HP, см. тут.
