The satellites will apply the rate limit to nodes by Id, if they are trying to check-in too often. The storagenode would try to check-in if the satellite said that the node was not reachable after the last check-in.
So, yes, it’s related to your configuration - something partially blocking access from the satellite in question.
Please, check your firewall and make sure that you have not blocking the traffic from said satellite (you should not block any traffic to the port of the node), please make sure that your firewall doesn’t have outgoing rules, if it has, then add another one to allow any traffic from any port of your node to any host and port in the internet.
