Help. open a site with blank

Here's some basic trouble shooting steps: - Clear your browser's cache - Check your firewall settings (if you know how) to see if there are any sites blocked - Start Run CMD Type "ipconfig /flushdns" without the quotation marks - Restart computer If after all that it still doesn't work, it could be that your ISP blocked that site. If that's the case, then you'll need to complain to them.

I think your proxy have set some security on access some web site and may be you entered site from blocked web site's list.You can't change that types of setting because only proxy administrator edit that proxy settings.If you want to confirm it you just open site from different system that means without use your current proxy use any other way to connect internet or this site is good you just contact your proxy admin.
