Error Lora-App-Server (Invalid Data Rate)

Can someone help me with this error? I received packets from my LT-100 Tracker but I dont know what this error means, its everything ok?

You probably have configured the gateway discovery feature (web-interface, under network-servers) with invalid configuration. Unless you’re planning to use this feature, I recommend you disable it.

Thank you so much, now it doesnt show this error.
