This is mean that something is preventing your node to be available from outside for this satellite, i.e. your node is considered as totally offline.
You may use these scripts to see when your node was offline:
The next step is to fix your node’s availability, i.e. check your firewall to do not block incoming connections to the node’s port and do not block outgoing connections from any port of your device to any address and port, your router to do not block incoming/outgoing connections with “smart” functions like DDoS protection, its firewall, throttling, and finally - your ISP (some ISP doing a “smart” protection for you, blocking “suspicious connections” and/or p2p).
