Did it solve? Also Check out Arcware CloudRT. It’s a free-to-start unreal streaming cloud service. There you have everything ready to use. Just upload your project and Stream with multiplayer. But in any case, if you stumble upon something, they also offer support (first-time free).
*they are not using AWS or Google to stream; they built their own GPU cloud specially made for Unreal Engine streaming.
