I asked what I thought to be a detailed question but with no answers or comments
On my personal opinion, there are too many things that could have caused the problem that you've described in your question.
Yes, your question is detailed, but the problem described therein is relatively complex. The solution is not quite obvious. It is impossible to provide a precise correct answer that will resolve the problem fast just based on the data you've provided.
Compare this to a question like "How do I set FTP proxy settings in Firefox?". A very precise and detailed answer can be given to this question. While yours is like a technical support request.
It would be possible to resolve your situation but it will require some effort from those who will try to help you and I guess people do not want to invest their effort in resolving this particular problem.
Probably it will draw more attention if there would be bounty associated with the question, because people will feel that they can get something back from their effort.
