GetAdusSettings() conn is null
This is a debug value in the code that is always generated behind the scenes, the current release is echoing it out in normal functionality. It just has a "null" value, which is expected behavior. This will be fixed in the next release of 2FA / ADUS
VerifyConnectionState() is unable to re-establish a valid connection to the database.
This is the AADBHelper.dll checking the database connection to make sure its valid. The message means that it needs to re-connect, and will without user interaction (AADBHelper.dll checks the connection every time an action occurs). This is expected behavior, however this should only be echoed out in debug mode. This will be resolved in the next version of 2FA.
