Windows Vista HTTP requests stop working

Solution 1:

I would guess that it's probably your anti-virus software or firewall. As wil said, you should also check your proxy settings. This may be strange, but I've noticed that the StumbleUpon toolbar will make my http requests time out. I try using different browsers, and the http requests still time out. But, when I disable the StumbleUpon toolbar, then there are no more timeouts.

Solution 2:

First things to take a look -

Firewalls, Anti-virus, Anti-Malware....

Development tools? Fiddler, or any other proxy server...

Check your proxy settings in general.

Personally, I would install Wfetch and see if I get any luck.

Also, if you have any Virtualisation software, installed do you get the same problems from browsing the internet in them?

Lastly, go in to safe mode with networking and try again and see if you still have the problem.
