RisingHF Gateway (RHF2S008) status showing not connected in TTN Server

Hello everyone,

I am using RisingHF Gateway (RHF2S008). We have connected that with TTN. When I am sending data(uplink) through the node, we are able to see the data in TTN, that means the gateway is connected to TTN but in console > Gateway > it shows that the gateway is “not connected”.
I have also attached screenshot of gateway status and the data sent by node.
