I am just not well enough up-to-speed on setting up such a server on my local network and simply have to live with what I can manage to set up, I'm afraid.
This is a fairly new requirement and I am still working out the workflow to get what I need. It does seem I am having better luck with getting changes pushed to my NAS.
For now, I will consider this issue resolved.
As for the 'Commit' panel, after having tested various 'file show options' via the several buttons at the top, I think I understand the GUI a whole lot more and seem to be able to manage cloning, pushing & pulling with some success.
Thank you
