Chrome not connecting to the internet on Ubuntu 16.04

You can reboot your router, modem, or both. these are some basic hacks which can help you before searching for further troubleshooting.analys your laptop's hardware Wi-Fi switch.

If you're using a wired connection, assure the ethernet cable is plugged tightly into both the computer's ethernet port and the router's ethernet port. Certainly, this may seem a bit obvious, but it's simple to miss a crashed switch or disconnected cable.

I have found a solution and resolved the issue. Basically when you open Ubuntu GUI network icon in the setting, you get wireless, wired , mobile broadband, and network proxy tabs. In that I went to the network proxy, found some really unhelpful proxies(http proxy, https proxy,ftp proxy, socks host) set to some wired addresses. So I deleted everything from there and changed the proxy auto mode to manual mode. After that everything worked well.

What I can't figure out is how Firefox overridden this setting while chrome wouldn't do such a hack around. You are reading this, and know how firefox override this, let me know. Thank you! :-)
