RN2483 Arduino Node with Liard LoRaWAN Gateway to work in India

Hi I have the RG186 gateway from liard which supports frequency from 863 to 870 MHz. The end node will be an Arduino with RN2483.

I was successful in communicating between both using the 868Mhz freq. but when I change the freq to Indian, the end node seems to work fine (based on what i see on serial monitor) but gateway does not receive anything

In the gateway settings on thingspeak console, I have set the frequency to 865-867Mhz as shown below but still the gateway seems to work at 868MHz bcs when I program the node to work in 868 I get data but when I change it to 865-867Mhz I get none

I did not find anything written on the gateway manual which allows setting frequency. So where should I look for problems on the gateway side or on the node side ?
