The reason why marantz can't update is because of the Port/TCP/IP is block by the router/ISP(unlikely by ISP). if you are using a router:
1: Log on into your router
2: Set your marantz receiver's IP address or MAC address into DMZ zone, (can by found at firewall settings in your router)
3: and try updating again.
And remember to remove your marantz receiver's IP address or MAC address from DMZ after the update is done.
