Any ideas?

Not really.

Try enabling JSON-RPC in Kodi Debugging > Component Logging. Upload both your kodi.log and the log from texturecache.py (add "@logfile=c:\tc.log").

It could be a problem with ipv6, you can force ipv4 with "@rpc.ipversion=4".

Outside chance of it being a problem with Python 3.4, which I've never tested.

Many thanks for the reply. I am not sure how to attach the logs. Please let me know...
Until then, below an extract:

1. Kodi.log
