The CloudBox has three different flashing Cloud LED patterns (Cloud logo on top of the CloudBox):
Solid blue light: The CloudBox is connected to power, local network, internet (Pandora CloudCover service), and is streaming correctly.
Flash, flash, pause: This indicates a connectivity issue; the CloudBox is not connected to the network. This is what you are going to see when first setting up a CloudBox, and it hasn’t yet been connected to the internet.
Flash, flash, flash: This is an API request failure. This could be where a firewall is blocking access from the CloudBox to the Pandora CloudCover API.
Long flash, long flash, long flash (about 6 second flashes): This is a media request failure. This is what you are going to see if Media is being blocked on your firewall.
