Kodi Remote Not Working

Hey all,
This is my first time posting here and I am very new to Kodi. So currently I have some Walking Dead episodes I want to watch on my TV, which I can do just fine. However, I can’t control it from my bed unless I use a Bluetooth mouse. I learned you could download an app to do this so I got Kodi Kore and Yatse, both I could not get to work. I followed many tutorials, I have put in the port number, allowed “remote control via HTTP”, typed in the correct username and password, and IP address, but it can not connect. I am running Kodi on Android 4.4.2 but I’ve tried it on so many other devices with the same result. Including the newer version.

Any help would be greatly appreciated,
Thanks!
