[Solved]Chrome cannot access Internet

All of a sudden I found my Chrome cannot access internet. In the beginning I thought it's a network problem, especially when I was in office using company proxy.

But I found that Internet Explorer is running, and even Chrome Canary is working normally.

I looked at all posts by didn't find any working solution.

Luckily I found out the root cause:
when I go to chrome-->Settings-->Advanced Settings
I found that change proxy settings is grayed out and it says "Your network proxy settings are being managed by an extension"

This makes me realize that there must be one extension that hijacked my network traffic. Then it is simple:
I found it's a AD blocker I am using, and I simply need to disable it.

Chrome is working well again.
For people might have similar problem, please check the extension you are using if Chrome cannot access internet, and you don't need to do things like uninstall and reinstall Chrome etc.
