Netflow Stopped Netflowing. We have been netflowing for years just fine

Greetings -

Updated to 2023.3 on September 12th. Everything has been fine.

On Monday 10/2 PowerShell Monitors stopped working correctly and had to disable them.

On 10/4 Netflow stopped working.

Time is fine on SQL DB.  Checked with DBA and there is very little traffic on the Netflow database. 

Not sure where to check for issues next.
