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

2. texturecache.log:

OK, got it to work. Had to also specify the allow remote programs to control Kodi setting in services.
Strangely enough this help message came out only when running with python 2.7.

Thanks a lot for your response and help.
