c# - ServiceStack based REST service gives timeout for log running process

Question

I need to run a 1-time long-running operation (around 10 minutes) via a ServiceStack service. I run this all on my local machine with ServiceStack running on IIS and .NET 5. Now it gives a timeout and I have no clue what is the cause (I also checked my IIS settings by the way). Part of my code (I removed some not relevant code):

static async Task Main(string[] args)
{
   var jsonServiceClient = new JsonServiceClient("http://localhost/services");
   jsonServiceClient.Timeout = TimeSpan.FromMinutes(20);
   await CorrectCreationDates(jsonServiceClient);
}

private static async Task CorrectCreationDates(JsonServiceClient jsonServiceClient)
{
   var request = new CorrectCreationDatesRequest();
   var result = await jsonServiceClient.PostAsync(request);
}

This is the exception:

System.Net.WebException: 'The operation has timed out.'

This exception was originally thrown at this call stack: ServiceStack.AsyncServiceClient.SendWebRequestAsync(string, string, object, System.Threading.CancellationToken, bool) in AsyncServiceClient.cs System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(System.Threading.Tasks.Task) System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(System.Threading.Tasks.Task) System.Runtime.CompilerServices.TaskAwaiter.GetResult() Gloneco.Importer.Program.CorrectCreationDates(ServiceStack.JsonServiceClient) in Program.cs System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(System.Threading.Tasks.Task) System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(System.Threading.Tasks.Task) System.Runtime.CompilerServices.TaskAwaiter.GetResult() ...

ServiceStack doesn't impose any request limits itself, any limits are imposed by the underlying HTTP Server, e.g. if you're using IIS checkout the How to increase request timeout in IIS answers.
