Why does kivy keep freezing when using python sockets? - sockets

Question

I'm working on a basic client-server desktop app project using kivy & sockets & threading.
The client & server work on it's own, however when I try to integrate it with kivy, python & kivy don't want to respond & yet no definitive error pops up.
Could i have some ideas as to how to fix this?
This is the code that freezes when i run it, if i take away the import server_sock it works as a general gui and doesnt freeze.
