Troubleshooting with Chrome is not the best method. You need to determine the scope of the problem. Are all of your clients on your network impacted? Using PING, can you ping past the proxy? Have you verified that name resolution is working?

For non HTTP traffic, are you able to get packets out past the ISP?

Once you determine where the problem is, better guidance can be given.

try to telnet to your proxy's port and see if you get any reply. Ping does not mean a lot.

You should be able to get a telnet response.

It would be helpfull if you could be a bit morre specific.
