If you can exclude high network latency, the first step to take is executing the Windows Update Automated Troubleshooter: you can find it here.
If this does not solve the problem, use the System Update Readiness Tool, described in the Microsoft Knowledge Base article 947821; if neither this tool fixes the issue, reset the Windows Update components as per Microsoft Knowledge Base article 971058.

Firstly, we could stop the Windows Update and install KB3050265, KB3102810 in the links below.
Or we could stop Windows Update service and empty C:\Windows\SoftwareDistribution folder to check.
Please Note: Since the website is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.
If the issue still insists, we could reset the Windows Update Components and follow the detailed steps to check.
Hope it will be helpful to you
