Connection to cast to a firestick

I’m not seeing any error mesages… alll i want to do is conect every time to my firestick… I’m sick of nortons crap interfering.
Now I’m at the point of unistalling it because of how so called smart it is. It won’t give access to my own devices. they’re nobloody threat and Nortons should know better. Sort this shit out Nortons support.
