Yesterday I was trying to set minimal privileges for Apikey, so I built a dummy logging application.

I used that application from 10:00-19:00 and then the Elastic search stopped showing logs. Since yesterday 19:00 **I am unable to get the any logs from the exact same application.**

C# code:

```auto
using System;
using Elastic.Ingest.Elasticsearch;
using Elastic.Ingest.Elasticsearch.DataStreams;
using Elastic.Serilog.Sinks;
using Serilog;
using Serilog.Core;
using Serilog.Events;

class Program
{
    static async Task Main()
    {
        var loggerConfig = new LoggerConfiguration()
            .MinimumLevel.Verbose()
            .WriteTo.Console()
            .WriteTo.File("logs/myapp.txt", rollingInterval: RollingInterval.Day);

        var apiKey = "SECRET";
        loggerConfig.WriteTo.ElasticCloud(
            "CLOUD_ID",
            apiKey,
            opts =>
            {

                opts.DataStream = new DataStreamName(
                        "type",
                        "dataset",
                        "namespace");
                opts.BootstrapMethod = BootstrapMethod.Failure;
                opts.MinimumLevel = LogEventLevel.Information;
            },
                    levelSwitch: new LoggingLevelSwitch()
                );

        Log.Information($"Hello, {apiKey} {DateTime.UtcNow.Second}!");
        Log.Error($"Hello, {apiKey} {DateTime.UtcNow.Second}!");
        Log.Debug($"Hello, {apiKey} {DateTime.UtcNow.Second}!");
        Log.Fatal($"Hello, {apiKey} {DateTime.UtcNow.Second}!");
        Log.Warning($"Hello, {apiKey} {DateTime.UtcNow.Second}!");
        Log.Information("Hello, world!");
        using var l = loggerConfig.CreateLogger();
        Log.Logger = l;

        var str = "a";
        for (int i = 0; i < 1000; i++)
        {
            str += i;
            str += "\n";
        }

        Log.Information(str);

        int a = 10, b = 0;
        try
        {
            Log.Debug("Dividing {A} by {B}", a, b);
            Console.WriteLine(a / b);
        }
        catch (Exception ex)
        {
            Log.Error(ex, "Something went wrong");
        }
        finally
        {
            await Log.CloseAndFlushAsync();
        }
    }
}

```

The connection is made between my application and Elasticsearch, since Index template is created, but I cannot display logs on discovery page.
