WordPress 4.3.1 update

Hi,
I have updated my website with WordPress 4.3.1 but it gives me an error:
An automated WordPress update has failed to complete – please attempt the update again now.

Have updated three times but this error still persists how can I check what this error is being caused by so I can attempt to fix it? It all seems to be working OK apart from this constant error in my Admin @ https://www.epnet.co.za
