For this article we assume you have set up the Online Content Vault correctly within CircuitStudio and have internet connectivity that isn't blocking (firewall, gateway, proxy) any content.
Domains used by the online vault can include *.altium.* including installation.altium.com, activation.altium.com, portal2.altium.com, portal2.altium.eu, portal2.altium.com.cn, portal1.altium.com, portal1.altium.eu, portal1.altium.com.cn and partscatalog.webservice.altium.com.
The issue is that, on starting CircuitStudio and bringing up the Vault Explorer panel you can see the folder structure but there are no components listed.
Try switching to a different folder and you should see the 'spinning icon' indicating that data is being retrieved.
Once a list of parts is shown you can switch back to your original folder and it will be populated.
