SeriLog won't log to railway?

Question

Hey guys, 
dumb question incoming...

I tried to setup serilog so i can log easier.

Doing this in Main()
`using var logger = new LoggerConfiguration()
                        .MinimumLevel.Debug()
                        .Enrich.FromLogContext()
                        .WriteTo.Console(outputTemplate: "[{Timestamp:HH:mm:ss} {Level:u3}] [{SourceContext}] {Message:lj}{NewLine}{Exception}")
                        .CreateLogger();`

Then this in ConfigureServices:
`// Konfiguriere den DI-Container
var serviceProvider = ConfigureServices(); `

`        services.AddLogging(loggingBuilder =>
        {
            loggingBuilder.ClearProviders();
            loggingBuilder.AddSerilog();
        });`

And this is a test log after ConfigureServices:
`var _logger = serviceProvider.GetRequiredService>();
_logger.LogDebug($"ENVIRONMENT={Environment.GetEnvironmentVariable("ENVIRONMENT")}");`

A normal Console.WriteLine() is shown in railway.

Any help is highly appreciated
