Check your Internet connection
Check any cables and reboot any routers, modems or other network
devices you may be using.
Allow Chrome to access the network in your firewall or antivirus
settings.
If it is already listed as a program allowed to access the network, try
removing it from the list and adding it again.
If you use a proxy server…
Check your proxy settings or contact your network administrator to
make sure that the proxy server is working. If you don't believe you should
be using a proxy server:
Go to
Applications > System Preferences > Network > Advanced > Proxies
and deselect any proxies that have been selected.
