How do I play Xbox remote play with the Xbox off?

It’s required the power option in your console is set to “sleep”. Without this mode, remote play isn’t going to work.
Please review if you have this power mode enabled.

If you turn off remote play on the Xbox, then he will no longer be able to do so. I would imagine that the app is very likely signed into your account.

i also have a question or certain questions about the remote play. i want to really understand how remote play functions like all the ins and outs. so my first question is, are you allowed to use remote play when the console is off? because i tried the opposite of that Friday and it worked but if i were to turn the console completely off am i still able to access my games and play them through the Xbox app when the system is turned off?

I'm having the same issue.

but I figured something about this.

When TV that connected to XBOX is turned on. remote play works.

but when TV is turned off. remote play is not working.

if I turn on my TV first, then remote play from my PC . it works perfectly.

then if I turn off my TV. suddenly Remote play become very unstable and stuttering.

and it disconnected automatically in a minute.

I tested wireless and wired , both behaves same.

and most importantly , this issue not reproducing iPhone and android phone remote play.

mobile phone remote play works perfectly no matter TV is turned on or not.

Wow you are right! I recreated this behavior exactly.

It would appear that PC Remote Play has some dependency on the XBox's TV being on. This is a great find @DaewooKim1!
