OSC issues with Broadcast

Hey all,

I am working with the OSC server/client for a while now to control Unreal via Resolume for my plugin.
Currently the server/client are connected to localhost - 127.0.0.1

Some clients asked me to add an option to Broadcast, since they use Resolume/OSC with more plugins.
I tried setting the server/client on UE to 255.255.255.255, but it’s not working.

What can be the issue?
127.0.0.1 works (when Resolume is set to localhost)
255.255.255.255 doesn’t work (when Resolume is set to broadcast)

The problem must lie within UE cause other tools seem to work with Broadcast & Resolume.

Thanks a lot
