I am thinking now that last week I reinstalled Windows on my home computer, and I had to re install Teamviewer over the weekend. It is only since that reinstall that I have been unable to connect. I've uninstalled and reinstalled TV again as a test, did not help.
I did try connecting to this home computer from a friend's house, using the Teamviewer application instead of the web client. When I do that I connect without any problems. So it is only the unattended access using the web client that does not work.
Also, I had my wife look at the screen on my home computer while I am trying to connect from work using the web client, and it does seems to partially connect. The desktop wallpaper goes to black, and the Teamviewer app slides out from the lower right, saying there is a connection in progress. But on the browser I am trying to connect from, it says "authentication required" then all I see is a white page.
Thanks
