First, in case you're using a download manager or a proxy, try deactivating them. Next, try hard-resetting your router by turning it off and leaving it off for at least 30 seconds, then turning it back on. Now, try downloading Google Chrome using this link: https://www.google.com/chrome/browser/desktop/ If it still doesn't work, make sure that your firewall isn't blocking your downloads or that the server isn't set to automatically reject the download.
Lastly, try installing a different browser such as Firefox or Opera and downloading Chrome through them.
