Kore cannot connect to kodi

I have Kodi installed on Windows 10 laptop. Kore does see the laptop but will not connect. Using Fing on Android I am able to ping my laptop. I have tried changing all the settings for the remotes and controllers to off then on again. I have also reset my network. At some point in the past it has worked with no problems. I don’t think that I have made any changes to my network.
