Update repository does not show latest updates

[Cookiesmonster]

Hi,

Running VMware vCenter Server 5.1.0 build 947673.
Would like to update my ESXi hosts from 5.1u3 to 5.1u9 using update manager

When running the scheduled task to download the updates the most recent update is 14-06-2016
Test connection at update manager --> configuration --> test connection gives no errors

The following URLs have been successfully accessed:

Running my vcenter server on server 2008 r2 Enterprise

How can i accomplish to have the latest updates visible in the repository?

Based on the vCenter build, it is on vCenter Server 5.1.0b.  It is recommended to keep vCenter on an equal or higher versions to the ESXi hosts.  If you can, upgrade vCenter first then look for updates again.

What exactly do you expect to see, i.e. what's missing? The latest patch bundle for ESXi 5.1 was released at 24-05-2016. For details about what's been updated after v5.1U3,  see e.g. https://esxi-patches.v-front.de/vm-5.1.0.html
