Did you ever get this working again sir?
Are you using QTS-4.3.6? They say 4.4.1 has too many bugs.
This is a good website article:

But don’t change anything just yet. Tell use what you see. Take screenshots of any errors. The reason for going slowly is because you said it was working before.
Can you connect with either of these secure addresses?
