PowerProtect Data Manager: SQL Agent discoveries do not show any assets under Assets/SQL DATABASES

Assets > SQL DATABASES do not show any SQL Databases after discover is run manually several times.

In SQL Server, the ADM log shows (ADM log: C:\Program Files\DPSAPPS\MSAPPAGENT\ADM Agent\logs):

...
(

Disposition: form-data; name="results"; filename="C:\\Windows\\TEMP\\ecdmruncmd775979743"
Content-Type: application/octet-stream

{
    "response": {
        "APIVersion": "2.2",
        "applicationInstances": []
    },
    "errors": [
        {
            "type": "systemErr",
            "text": "General exception when detecting AAG information for SQL Server '<SQL SERVER name>'.\n"
        }
    ]
}

PowerProtect Database Manager Console fails to connect to the SQL server using the LocalSystem Account.

Procedure:

1. On the Windows SQL Server, go to services.msc.
2. Select ADM agent.
3. Right click and select Properties.
4. Click Log On.
5. Click This account and input a Windows user with access to the SQL server.
   Note: Sometimes, the software works better if the Windows user is a Domain Admin as well. If possible, ensure that the Windows user has access to SQL Server and is a Domain Admin as well.
6. Restart the service.
