Opentelemetry not working. Getting timeout when exporting spans

[zubaiersayed]

Expected Behavior

I expect the trace data to be available in Elastic UI.

Actual Behaviour

With this config in application.yml file I get timeout:

I have these dependencies in my gradle build file:

implementation("io.micronaut.tracing:micronaut-tracing-opentelemetry-http")
// For OTLP exporter
implementation("io.opentelemetry:opentelemetry-exporter-otlp")
// For annotation processing
annotationProcessor("io.micronaut.tracing:micronaut-tracing-opentelemetry-annotation")

otel:
  exclusions:
  - "/health"
  resource:
    attributes:
      service.name: "application-name"
      environment: test
  exporter:
    otlp:
      protocol: http/protobuf
      compression: none
      endpoint: "http://hidden.apm.eu-west-1.aws.cloud.es.io"
      headers:
        Authorization: "Bearer hidden"
        Content-type: "application/x-protobuf"
      timeout: 30s
  traces:
    exporter: otlp
  metrics:
    exporter: none
  logs:
    exporter: none
