The connection to localhost was interrupted.

Here are some suggestions:

• Reload this webpage later.
• Check your Internet connection. Restart any router, modem, or other network devices you may be using.
• Add Google Chrome as a permitted program in your firewall's or antivirus software's settings. If it is already a permitted program, try deleting it from the list of permitted programs and adding it again.
• If you use a proxy server, check your proxy settings or contact your network administrator to make sure the proxy server is working. If you don't believe you should be using a proxy server, adjust your proxy settings: Go to the Chrome menu >Settings > Show advanced settings... > Change proxy settings... > LAN Settings and deselect the "Use a proxy server for your LAN" checkbox.
