I realized that if I run the patchnotification from the task scheduler I always had an installation left to install.
So I ran the cmd file and discovered this
why doesn't it install?
Solved! Go to Solution.
The ArcGIS Server (10.8.1) Date Fields Performance Improvement Patch was made available on 26 May, 2021 PST.
Do you still see any uninstalled patch if you run the PatchNotification tool manually now? Esri keeps on releases patches to address multiple bugs and bring improvements/ enhancements for its products.
Yes, the same thing is occurring for for the Portal PatchNotification at 10.9. For me at least, the PatchNotification did not throw the remote URL error on the Server PatchNotification at 10.9. For DataStore at 10.9, unknown. There has not been any patches released for DataStore PatchNotification tool to try to download.
