[google-chrome] "Proxy server connection failed" in google chrome

My Google Chrome has stopped working & I don’t know why. proxy server part is unchecked & Automatically detect settings part of LAN setting is checked.
But when I want to load any site on it this message appear:

Proxy server connection failed.

I searched but no result! Is there any way to solve this problem?

I'm using windows 8.
I uninstalled chrome and Install a newer version, but the same error exists & doesn't allow me to use chrome.
my connection to Internet is OK & I can ping www.google.com, or use other browsers.

Internet explorer has a reset to factory button and luckily so does chrome! try the link below and let us know. the other option is to stop chrome and delete the c:\users\%username%\appdata\local\google folder entirely then reinstall chrome but this will loose all you local settings and data.

Google doc on how to factory reset: https://support.google.com/chrome/answer/3296214?hl=en

1. Open Google Chrome.
2. Click Menu on the upper right side. Beside the STAR symbol (Bookmark).

5. Click Change proxy settings.
6. On the Connections tab, click LAN settings.

Hope it helps .

Try following these steps:

3. Go to Advanced Settings (its all the way down).
4. Scroll to Network Section and click on ''Change proxy settings''.

6. Click on ''LAN settings''
7. Un-check ''Use a proxy server for your LAN''
8. Check ''Automatically detect settings''
9. Click everything ''OK'' and you are done!

I had the same problem with a freshly installed copy of Chrome. If nothing works, and your Use a proxy server your LAN setting is unchecked, check it and then uncheck it . Believe it or not it might work. I don't know if I should consider it a bug or not.
