Adobe Reader AUSST error

Hello

We have a local Adobe Update Server and previously Creative Cloud apps, Acrobat and Reader were updating normally.

An issue we are having is that our Acrobat and Reader no longer update beyond 19.010.20091

According to the log t appears as though the download manifest files are not present on AUSST.

I have performed an incremental update from Adobe's servers and the file is still not present at that location.

I have tried to copy and rename the AcrobatDCManifest2.msi to AcrobatDCManifest3.msi to see what happens when checking for updates I am prompted to install 19.010.20091 again, this indicates to me that the workstation is correctly configured, but the server is missing that file.

Is there any way to resolve this without performing a full sync?

Thank you

Joseph
