Default [Q] samsung link between s4 and 10.1 Tab Pro

Hey guys,

Firstly apologies if this is an already existing thread.

Basically I bought the relatively new 10.1 Tab Pro running 4.42, and I'm having trouble connecting it to my Samsung galaxy s4 via Samsung link. When I open the application on either device I can clearly see each device but when I try and connect to either device it comes up with the error message : unable to connect to the device. Check the connection status.

Now I've researched this issue and a majority of the time people say to clear the All share data and cache. I've done this and it still does not work.

Are there any particular security settings I should be allowing on either device ?
