Not able to read values from Azure KeyVault. The specified user does not have a valid profile

We have multiple servers on which we are hosting an ASP.NET website on IIS. In the website we are trying to fetch values from Azure KeyVault.
In one server for some reason it fails to read the values from Azure KeyVault with an error 'The specified user does not have a valid profile'. We have done investigation, double-checked configuration, permission rights on files - everything looks okay. Also tried to adjust profile in IIS, nothing helped.
Here is the stack trace:
Exception information:
Exception type: ConfigurationErrorsException

Has anyone experienced a similar issue?
Any help will be appreciated.

I have answered a similar question here: Function app in Azure could not load file or assembly 'Microsoft.Extensions.Logging.Abstractions'
Do check out - it can be because of same reasons. There may be a nuget package which requires different version of Microsoft.Configuration.ConfigurationBuilders.Azure: 2.0.0. But, you have a version installed which is incompatible.

After doing some debugging we have found the issue. It turned out that under Environment variables for the user we had everything correct, but under environment variables for system we mistyped AZURE_TENTANT_ID. Explains why it was working as a console application (run as current user) and not as a Windows Service (run as system)

How to Encrypt the App.config file in .NET Core?

I created a new .NET Core 2.1 Console project.
I added Config.xml:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<connectionStrings>
<add name="MyLocalSQLServer" connectionString="Initial Catalog=aspnetdb;data source=localhost;Integrated Security=SSPI;" providerName="System.Data.SqlClient"/>
</connectionStrings>
</configuration>
In Program.cs:
class Program
{
static void Main(string[] args)
{
Console.WriteLine(ConfigurationManager.ConnectionStrings["MyLocalSQLServer"]);
}
}
With aspnet_regiis, I encrypted the configuration file:
RENAME "C:\repos\ConsoleApp7\bin\Debug\netcoreapp2.1\ConsoleApp.dll.config" web.config
aspnet_regiis -pef "connectionStrings" "C:\repos\ConsoleApp\bin\Debug\netcoreapp2.1"
RENAME "C:\repos\ConsoleApp7\bin\Debug\netcoreapp2.1\web.config" ConsoleApp.dll.config
Finally, I ran the app:
dotnet "C:\repos\ConsoleApp7\bin\Debug\netcoreapp2.1\ConsoleApp.dll"
I got the error:
Unhandled Exception: System.Configuration.ConfigurationErrorsException:
Failed to decrypt using provider 'RsaProtectedConfigurationProvider'.
Error message from the provider: Operation is not supported on this platform.

This trick works to encrypt app.config with the old .NET Framework, but it isn't supported by .NET Core.
The purpose of this is to test migration from .NET Framework to .NET Core.
How can I encrypt app.config in .NET Core?

IIS 7.5 virtual directory runtime error

I have IIS 7.5 With one web site

As the error message suggests, you need to convert the virtual directory you have added into an application. Right click it in IIS and you should see the option to do this.

(SEH)Exception initializing Nlog

I get the error at the end when I try to start a project I'm working on from Visual Studio. It worked fine until a few hours ago. After some minor unrelated changes it stopped working when starting from Visual Studio. It works fine when run from explorer. Even old version vom revision control (where this part of the code is exactly the same and has worked without any problems) behave the same way so it doesn't seem to be a problem in my code.
The code at Program.cs:line 14 is the following:
private static NLog.Logger logger = NLog.LogManager.GetCurrentClassLogger();
Any ideas on how to solve this?
