AxObjectXMFDisplay Rumba Mainframe Screen Scraper: Unable to Connect to HostSession

Hi All,

I have a VB Project that connects to Mainframe Systems using Rumba Runtime 6.0
Recently I migrated this VB Project to VB.NET and now i am facing difficulty in consistantly Connecting to the Mainframe Host. Here is the function that is used. The Hostname that I use is a IP Address. Any help is greatly appriciated as this is a rarely used software by people.

Code:

 
 Public Function TN3270_ConnectToHost(ByRef HostSession As Object, Optional ByRef HostName As Object = Nothing) As Integer
  Dim I As Short
  
  'Return if already connected

        If (UCase(Trim(HostSession.HostInterface.Interface.ConnectedName)) = UCase(Trim(HostName))) Then
            TN3270_ConnectToHost = 0
            Exit Function
        End If
