I was trying to access some websites this morning, but I discoved I couldn't access some sites, such as gmail (I know the sites were up because I could get on to them from other people's machine). If I used firebox, it gave me "The connection was refused when attempting to contact www..com", I also tried other browsers such as IE, but still got the same problem. I have tried hours to find a solution to fix the problem, but effortless so far. One thing I noticed was that all these sites I couldn't go seemed to require secure connection. Does anyone have the similar experience? How do you solve the problem? Please help me on this, I am really desperated right now, your help is highly appreciated. Thanks a billion in advance.
