["Start Remote Control Session" Grayed Out]

@Paul I am curious, I want to use my home PC, with this remote feature, I have a dj mixing and live streaming site, the phone app, to remotely control the music and other apps on my PC is top notch, what I am curious though... Is that I can't use remote access, I mean I only want it for 1 pc and I can't find anywhere to pay or stuff like that? Is there any way to bypass the greyed out button?

Just thought it might work after watching Linuse's video, but still nothing

So, I want to use Pulseway to control my pc from a distance when I play music... But I can't do it, I dunno why, can anyone help me? I followed the steps, but it says that the remote control feature is not available... I do not know why?
