Looks like 5.3 has a different recommendation for includes. Replace the header that it's complaining about with ```#include "IPAddress.h"``` (should be at the top of udpcomponent.h)

You may have better luck using the v2.0.0 from UE5.0 on 4.27. It's likely 4.27 had some api changes. Ensure you're compiling the plugin correctly (https://github.com/getnamo/UDP-Unreal#blueprint)

Without error codes pointing directly to lines in the plugin, I'm unsure if it's plugin related.

Not sure how the underlying udp system handles UDP multicasts, you'd need to dig into e.g. https://docs.unrealengine.com/4.26/en-US/API/Runtime/Sockets/ISocketSubsystem/. Keep in mind UDP is an unreliable stream.

add a udp component to an actor first then from that component your functions will show up. See https://github.com/getnamo/UDP-Unreal#how-to-use---basics for instructions on how to use.

For this use case I recommend using https://github.com/ncsoft/Unreal.js. There are some react-umg examples using that https://github.com/ncsoft/React-UMG.

This plugin is currently only configured for windows. Would need some outside help to bring other platform support.

A timeout seems like a reasonable way to go. We can have a heartbeat from unreal e.g. every 10-30sec and if it doesn't receive it, exit the process. Likely can...

I usually hit the latest production engine with most of my plugins within a month or so of release, if you need it sooner you'll need to check the compile...

5.2 release made here: https://github.com/getnamo/NodeJs-Unreal/releases/tag/v1.4.0 it still has #41 issue sometimes. May require starting the script twice to resolve.
