Description

Hi,

Is possible that the timeout configuration is not being used in Akka 10.0.10?

  val akkaVersion = "2.5.6"
  val akkaHttpVersion = "10.0.10"
  //Akka
  "com.typesafe.akka" %% "akka-actor" % akkaVersion,
  "com.typesafe.akka" %% "akka-testkit" % akkaVersion % Test,

  //AkkaHttp
  "com.typesafe.akka" %% "akka-http" % akkaHttpVersion,
  "com.typesafe.akka" %% "akka-http-spray-json" % akkaHttpVersion,

  //To be compatible between Akka and Akka http
  "com.typesafe.akka" %% "akka-stream" % akkaVersion,

Doing:

val timeoutSettings =
        ConnectionPoolSettings(context.system.settings.config).withIdleTimeout(10 minutes)

      http.singleRequest(
        HttpRequest(
          method = HttpMethods.POST,
          uri = endpoint,
          entity = rqEntity
        ), settings = timeoutSettings)

I'm getting: akka.stream.scaladsl.TcpIdleTimeoutException: TCP idle-timeout encountered on connection to [localhost:9080], no bytes passed in the last 1 minute.

Research direction
Investigate the idle timeout configuration in Akka HTTP 10.0.10. The issue reports that setting an idle timeout via ConnectionPoolSettings.withIdleTimeout is not respected; instead, the default 1 minute timeout is used. Look at the ConnectionPoolSettings source code and how the idle timeout is applied in the singleRequest method. Check if there were any changes in version 10.0.10 that might have broken this feature. Consider looking at related issues or the Akka HTTP documentation for known workarounds.
