Docker OpenTelemetry Collector contrib instrumentation issue with .NET

Question

I am trying to setup OpenTelemetry Tracing with exports traces to Jaeger and Datadog Here is extracted example that I used. All containers is running and no errors in console.

For jaeger url directly it is working and I see my traces but when I trying to change URL to otel-collector it is not sending traces. I don't see it on otel-collector container logs and in my jaeger

My docker-compose.yml

services:
  otel-collector:
    image: otel/opentelemetry-collector-contrib:0.95.0
    ports:
      - 1888:1888 # pprof extension

      - 13133:13133 # health_check extension
      - 4317:4317 # OTLP gRPC receiver

Program.cs setup

services.AddOpenTelemetry()
                .ConfigureResource(resource => resource.AddService(AppTracing.TelemetryServiceName))
                .WithTracing(tracing => tracing
                    .SetResourceBuilder(ResourceBuilder.CreateDefault().AddService(AppTracing.TelemetryServiceName))
                    .AddSource(AppTracing.SourceName)
                    .AddAspNetCoreInstrumentation()
                    .AddHttpClientInstrumentation()
                    .SetSampler(new AlwaysOnSampler())
                    .AddOtlpExporter(otlp =>
                    {
                        otlp.Endpoint = otlpEndpoint;
                    })
                    //.AddConsoleExporter()
                );

My controller action that I use for test

[HttpPost("test-datadog")]
        public void SendBatchTraces()
        {
            var session = Random.Shared.Next(0, 100);
            foreach (var index in Enumerable.Range(0, 1000))
            {
                using var activity = AppTracing.Source.StartActivity($"Sending trace number: {index}");
                activity?.SetTag("Session", session);
            }
        }

I want to send it to collector and then distribute it to jaeger and datadog.

Maybe I can somehow see detailed log for collector or for my .NET app to check any connection issues? For now in console of each app there is no any errors.

Thank you very much for any suggestion!
