Help connecting to a website please

So for the past three months I have been able to connect to a gaming site and all of a sudden starting 3 weeks ago I have not been able to connect to it anymore. My friends can still get on it, its just me. I can still connect to every other site. When opening on ie it says "navigation to the web page was cancelled. On firefox it says the url is not valid and cannot be loaded. I did ipconfig /all and here are the results.
