Strange Error using IPv4Address

[anonymous_user_550bff35]

Hey every one.

I am trying to learn some UDP networking. But I am already running into some problems.
Every time I try to use IPv4 in my code I get this long list of errors.
At the top of my Actor i include

#include "Runtime/Networking/Public/Interfaces/IPv4/IPv4Address.h"

I only add
FIPv4Address ip;
to the actor and i am already getting these errors.

I did add “Sockets” and “Networking” to my build.cs
I hope someone can point me in the right direction.

Using #include "Networking.h" Instead of #include "Runtime/Networking/Public/Interfaces/IPv4/IPv4Address.h" Seems to fix the problem for me.
