like below fixes the issue There is no blocking UDT transport in Netty. If there is a good reason to add the old-I/O UDT transport, please let us know.

Netty : Blocking call to get a connected Server Channel?

Netty : Blocking call to get a connected Server Channel?

help you fix your problem You could create a blocking call, but I think you maligned the event based approach too quickly. This is a contrived example, just to make sure I understand what you're trying to do:
Netty Server starts A DataPusher service starts. When a client connects, the DataPusher grabs a reference to the client channel and writes some data to it. The client receives the pushed data shortly after connecting.
code :
DataPusher dataPusher = getMyDataPusherReference();

public void channelConnected(ChannelHandlerContext ctx, ChannelStateEvent e) {
   dataPusher.doYourThing(e.getChannel());  // do something in another thread....
}

I hope this helps you . No. SO_TIMEOUT has effect only for OIO socket transport. You should use IdleStateHandler and handle an IdleStateEvent in your userEventTriggered() implementation.

it should still fix some issue closeFuture.sync() is not for closing the Channel but rather allows you to block until the Channel is closed. For closing the Channel you would call Channel.close().
How can you safely perform blocking operations in a Netty channel handler?

like below fixes the issue If an operation in Netty takes longer time to complete or is blocking it is advisable to perform that in a handler that uses a separate ExecutorGroup so that the main EventLoop thread is not blocked.
You can specify that during the pipeline creation.
code :
static final EventExecutorGroup group = new DefaultEventExecutorGroup(16);
 ...

 ChannelPipeline pipeline = ch.pipeline();

 pipeline.addLast("decoder", new MyProtocolDecoder());
 pipeline.addLast("encoder", new MyProtocolEncoder());

 // Tell the pipeline to run MyBusinessLogicHandler's event handler methods
 // in a different thread than an I/O thread so that the I/O thread is not blocked by
 // a time-consuming task.
 // If your business logic is fully asynchronous or finished very quickly, you don't
 // need to specify a group.
 pipeline.addLast(group, "handler", new MyBusinessLogicHandler());

Hope this helps You are trying to use two incompatible versions of Netty. That is impossible.
Upgrading to Play 2.6 or later would solve this for two reasons:
code :
libraryDependencies ++= Seq(
  "software.amazon.awssdk" % "dynamodb" % "2.10.33" exclude("software.amazon.awssdk", "netty-nio-client")
)
