I did write a long message, and then closed the window, and I lost it [:(]
Anyway, what i was trying to say is that a few people had similar issues after moving our server to a different location on July 6.
I recently noticed that they are now able to access the website without any apparent reason why it worked. So unfortunately I don't have a clear solution.
It is important though to make sure that the issue is not on the local computer, but on the Internet connection.
I would try to find another computer (like a laptop) that works in a different location and try it on your connection. If it works, then the problem is obviously with your computer/software.
It could be some security setting or you might be infected with spyware or...
If the other computer does not work either, you could ask your ISP, but in my experience, they will blame it on our server, or your computer, but it might be worth a try. If that is the case waiting a little longer might resolve the issue.
I'm sorry I could not come up with a real solution... I am not such a great "tech" guru as they think around here.
Good luck! And please let us know how it was resolved when it resolves.
