[Ryan Steele]

Since Sept. 27, the following event has been logged once an hour in the Microsoft Azure AD Connect Agent Updater Admin log in Event Viewer (Applications and Services Logs > Microsoft > AzureADConnect > AgentUpdater > Admin):

Log Name:      Microsoft-AzureADConnect-AgentUpdater/Admin
Source:        Microsoft-AzureADConnect-AgentUpdater
Date:          2019-09-27 12:52:03 PM
Event ID:      32012
Task Category: None
Level:         Error

The Microsoft Azure AD Connect Agent Updater service failed to check for updates.

It looks like Azure AD Connect may have auto-upgraded on Sept. 26 to version 1.4.18.0. Is this a known issue?

There were many changes in that update and some unexpected issues with data getting removed, but I'm not aware of anything that would be causing your issue. take a look at https://docs.microsoft.com/en-us/azure/active-directory/hybrid/reference-connect-version-history to see if there is something i missed.
