Sophos Endpoint not updating! Can't work it out!

Hello,

I could well be completely dim, but I can't work out why my sophos has suddenly taken it upon itself to lack the ability to update. I have read loads of similar posts but I seem to be going round in circles. I have checked my indexing is turned off for it as suggested but that hasn't solved the problem.

Here's a transcript of the update log -

Thanks
