Help please with upnp and log

Can someone please help me. I am at my wits end. Someone is accessing kodi on my fire stick via upnp and its driving me crazy. I have a ton of logs but have no idea bow to read them. I actually has to go searching for these logs because when I did the loguploader it says it can’t upload. I need to figure out who. I have a suspicion but am not going to confront until I have all my ducks in a row. Someone…anyone? When I watch TV, I can see the pixelization of something else on my screen when I dont have picture in picture on my TV.
