DirSync Status's Last Directory Sync

Hello,

I'm using Azure AD Connect to sync my local Active Directory with Office 365. For the past few days I've started to receive the following message i.e. the directory is no longer syncing. As a test I added new objects i.e. users in my local on-premises active directory, ran the ADSync PS manually and they are not showing up in my Office 365 users.

I did run the 'Get-ADSyncScheduler' and confirmed the Sync Cycle is enabled.

I also ran the 'Start-ADSyncSyncCycle -PolicyType Initial' but that hasn't helped.

Finally, I downloaded and ran the IdFix - Directory Error Remediation tool and ran it, however, it did not yield any errors. Hence, i'm running out of ideas to fix this issue and welcome any thoughts, ideas to resolve this issue.

Thanks in advance!
