I am experiencing the same problem, except it is the other direction!!
I am sure this is related to port 59xx (or 58xx if you are using your
browser), not allowing you access etc.
Have you just installed or changed your firewall at home recently? This is
my problem, we have just upgraded the firewall at work, and although I
requested both port 59xx and 58xx to be opened, only 58xx has been opened -
net result - NO ACCESS!! Another problem is the connect speed, here I am
using 28.8 at both sites. This makes things very slow, but it does work!!
Perhaps there is somebody else who is more able to advise you on how to
solve this.
