Connect TTN GW to lora server

I have a RAK831 LoRa gatway and has been operated with TTN server.
I want to connect to my own LoRa server “” that built according to this.
What configuration should I do? I have changed the server to my IP address but it still shows on TTN server.

Thanks guys!

In order to help you, please share with us what components of the LoRaServer Project you did install on your gateway.

By the way,

Where did you change the IP? On which file of which component?
