-111 Failed to Connect to SBOCommon

Question

I am getting an occational error when I am trying to connect to one of our test databases with the DI API.
This is what the code looks like:
  oCompany = New SAPbobsCOM.Company
        oCompany.Server = "192.168.123.76"
        oCompany.CompanyDB = "Feb19_ForAuditors"
        oCompany.UseTrusted = True
        oCompany.UserName = "maanger"
        oCompany.Password = "manager"
        '** Disconnect from DB if connection present
        If (oCompany.Connected = True) Then
            oCompany.Disconnect()
        End If
        Try
            '** Attempt connection to DB
            lRetCode = oCompany.Connect
        Catch ex As Exception
            MessageBox.Show("Error upon connecting to " & oCompany.CompanyDB & Environment.NewLine & _
                        ex.Message, "SAPbobCOM Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
            Close()
        End Try
        If lRetCode <> 0 Then
            '** If there was a code other than 0 (connected) state why
            oCompany.GetLastError(lErrCode, sErrMsg)
            MessageBox.Show(sErrMsg)
        End If
Now normally my SAP B1 setup for the application itself is set to Used Trusted.  I started off using .UseTrusted = True but it would never let me connect until it supplied .Username and .Password
Now it seems it seems to fail more often now with both the username and password as well as being a trusted connection.
I can use SAP fine, but when I try to run my little app it says Failed to Connect to SBOCommon
Is there anything wrong in the above code? I would like to use the trusted connection because I don't want to have people type in their username/password each time they run this little middleware app nor do I want to store it on each machine.
Could it possible be an issue if my program crashes and the connection to the SAP database was not closed properly and it has to wait to timeout??
Just looking to figure this out

Tyler,
You state that you get the error "occasionally".  Does that mean that you do not get it all of the time?   If you do not get it all of the time, what is the difference/what has happened between the time that you do not see the error and the time that you do?  What version of Business One and patch level are you using?
Here is a note from the SAP Notes database that may help, but it has to do with db ownership and also may not pertain to your issue ...
