Azure Arc Server connected to Azure Update Manager Not Being Updated With Monthly Security Update

I am looking for some assistance with this issue. A manual check on the server finds the latest 2024-08 updates, however when I forced an update check in AUM, it yields nothing.

My schedules are working correctly, and daily defender updates are being applied successfully. Other servers are being updated correctly using the same schedule.

Log output from WindowsUpdateExtension.log
