Hello,
We have a standalone updater server. It was supposed to download all the subscriptions packages and the 2 UVMs connect to the updater server to get the packages and installed. We actually did the Windows update back on February 2024. However, when we tried to update the appliances to windows security update to 202409, we couldn’t find the subscriptions on the available list. The screenshot was below:

The updater server has full Internet access and test connection was success.
Below is part of the updaterService log:
