jcs

Actually just fixed it now its working. 

All I had to do was disconnect my laptop from any wifi network and then go and connect to the TV and it worked. Then i joined wifi once connected.

@jcs @jcs I had an issue with this as well.Never had any issues connecting up until a while back where it just wouldn't connect anymore.Not sure what set up you have but click notifications icon at bottom right of PC screen, click connect then click projecting to this PC.Where it says some Windows & Android devices can project to this PC when you allow them to, click on the box below & make sure it's set to Available everywhere.Below that, it says Ask to project to this PC, click on box below & set to First time only.This worked for me, hope this helps.

Thanks for the advise but after following what you suggested, it still does not work. No changes either , everything is the same as my post above. Any other ideas?

My windows 10 laptop that once connected great wirelessley to my TV now will not.

When clicking connect from the notification center, then  clicking on my LG webOS TV I see this on the TV screen

My PC name requests screen sharing to your TV with a magenta decline button, then shows unable to connect with screen share. Try again.

on windows 10 it says:   connecting, follow any instructions on your device then in yellow it says couldn't connect

TV is hardwired ethernet and laptop is on 5GHz wifi. Same laptop and tv used to connect no problem.
