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.

I had this error with VS 2015, in my case going to the project properties page, Web tab, and clicking on Create Virtual Directory button in Servers section solved it

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.
Specified argument was out of the range of valid values. Parameter name: site

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.

vs2017 just added in these lines to csproj.user file
<IISExpressAnonymousAuthentication>enabled</IISExpressAnonymousAuthentication>
<IISExpressWindowsAuthentication>enabled</IISExpressWindowsAuthentication>
<IISExpressUseClassicPipelineMode>false</IISExpressUseClassicPipelineMode>
with these lines in Web.config

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

При работе в управляемом приложении через веб сервис пользователь иногда получает сообщение:
Server Error in ‘/’ Application
С совершенно не вразумительным текстом описания ошибки и рекомендацией как поступить при этом.
Как решать указанную проблему?
Разделим саму проблему на две части:
Проблема Веб сервиса и проблема 1С.
Проблему 1С можно обнаружить и устранить, если запустить режим отладки Тонкого клиента и проверить работу управляемых форм, ответственных за место в котором происходит ошибка.
Здесь мы будем рассматривать половину относящуюся к Веб серверу.
В некоторых источниках пишут что указанная ошибка является характерной для хакерских атак, но в нашем конкретном случае о такой атаке речь идти не может, т.к. проблема возникает при обращении к сервису не из вне сети, а из интранет.
В переводе на русский язык ошибка звучит как: «Ошибка приложения вызванная на сервере. Текущие настройки сервера для этого приложения ошибочны, приложение было остановлено по соображениям безопасности в привентивном режиме.»
Рекомендация данная ниже отключает режим вывода сообщений, но не дает ответа как устранить причину появления ошибки, при условии правильности работы кода 1С во всех других режимах.
немного манипуляций и страница дает уже более понятную информацию:
Если ранее проблема была не понятна, то сейчас более понятно что ошибка относится именно к веб серверу и что вызывается именно привентивным прекращением работы приложения веб сервером.
Проблема же заключается в том, что .net имеет режим валидации исполняемого сервером кода, вот эта валидация и приводит к появлению указанной ошибки.
Для устранения ошибки рекомендуется выполнить настройки вебсервера:
1. ValidateRequest = «False»
например,если в конфигурационном файле у вас уже есть:
<% @ Page Language = «VB» AutoEventWireup = «False» Codebehind = «MyForm.aspx.vb» наследует = «Proj.MyForm»%>
то должно стать:
<% @ Page Language = "VB" AutoEventWireup = "False" Codebehind = "MyForm.aspx.vb" наследует = "Proj.MyForm" ValidateRequest = "False"%>
В более поздних версиях Visual Studio значение этого свойства можно получить на странице свойств, поэтому просто установите » ValidateRequest » на » False«. Любым способом установки можно получить тот же результат.
Примечание:
1.1. Если вы используете. NET 4, то вам необходимо добавить requestValidationMode = «2.0» в HttpRuntime раздел конфигурацииweb.config файла. Например:
<httpRuntime requestValidationMode=»2.0″/>
Если у вас еще нет раздела HttpRuntime в web.config, то это можно сделать такие настройки в разделе <system.web>.
Чтобы глобально выключить проверку запросов добавьте следующую строку в вашем web.config файла: <pages validateRequest=»false» /> раздела <system.web>.
2. Установить EnableEventValidation = «False» запретим проверку корректности события.
3. Установить EnableViewState = "False"
и
4. Установить нужное значение в ExecutionTimeout. В моем случае строка выглядит так: ExecutionTimeOut = «20»
Это верно для: NET 1.1,. NET 2,. NET 3.5 и. NET 4.0

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.

Question

We recently migrated to Office 365 Government E3.
All employees in our SharePoint group have been able to access SharePoint without issue… until this morning.
Admin users are able to select the SharePoint app from the Office 365 homepage and be directed to our organization’s SharePoint sites (https://xxxxxxxxxx.sharepoint.com/_layouts/15/sharepoint.aspx).
When any other (non-admin) user attempts these steps, they receive the following message:
Server Error in ‘/’ Application.
Runtime Error
Description: An
application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server
machine.Details: To enable the details of this specific
error message to be viewable on remote machines, please create a <customErrors> tag within a “web.config” configuration file located in the root directory of the current web application. This <customErrors> tag should then have its “mode”
attribute set to “Off”.<!-- Web.Config Configuration File --> <configuration> <system.web> <customErrors mode="Off"/> </system.web> </configuration>Notes: The current error page you are seeing can
be replaced by a custom error page by modifying the “defaultRedirect” attribute of the application’s <customErrors> configuration tag to point to a custom error page URL.<!-- Web.Config Configuration File --> <configuration> <system.web> <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/> </system.web> </configuration>
An admin and a regular user can attempt to access SharePoint on the same workstation, and, still, only the admin can view it.
I have read through forums regarding this message and they all say that it is an IIS issue. We installed IIS on 1 server this morning, which is when people started to report the issue. I stopped IIS on the server, but the issue remains. But, since we aren’t
hosting SharePoint ourselves and accessing it through a 365 subscription, I don’t think this should matter anyway.I also read that the web.config files should be edited at the following directory: C:inetpubwwwrootwssVirtualDirectories…
We don’t have that directory on the server that is running IIS (or on any other server, for that matter). The furthest
the directory goes is C:inetpubwwwroot-

The Microsoft Support team opened a ticket for this issue and it has been “resolved”. They had grant permissions to all of the users again.
Here it is, Barney style:
1.) Go to your site page (https://xxxxxxx.sharepoint.com/SitePages/Home.aspx(
2.) Click on the Settings gear icon on the top right, go to Site Settings
3.) Click on Site Permissions
4.) Grant permissions to your users
So simple, but something that I didn’t even think about because they could still access SharePoint via OneDrive and direct URL.
THANK YOU, DALE AND ETHAN!
