Glad to hear it's working right now, @GeeVee. To confirm, your Marantz is connected through WiFi? If it is, are you able to connect through Ethernet cable to see if you receive the same message?
In the meantime, if you haven't already, I can recommend power cycling your Marantz and router/modem to see if that will help. You'll want to unplug the devices for at least 5 minutes and then plug them back in.
If the message persists, let me know the time and date and I'll take a closer look. Thanks!
