PlexPy not starting

Recently installed PlexPy on my Windows 10 PC and it’s worked beautifully for the last week. Now it displays …

ACTIVITY
There was an error communicating with your Plex Server.

… and in my logs…

… any idea what’s happened ? Ran CCleaner across the PC last night before this happened, could just be a coincidence ?
