I am creating a mini game on Minecraft.
I installed the Spark dependency to create a web API from the game.
I bought a VPS on OVH under the ip 151.80.XXX.XXX
I installed a pterodactyl panel to facilitate the creation of the server.

Problem:
I can not access my Spark web api. It conflicts despite the change of host or port.

Here is my code

Spark.port(Config.getInt("api_port"));
Spark.before((request, response) -> { 
   response.header("Access-Control-Allow-Origin", "*"); 
   response.header("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS"); 
   response.header("Access-Control-Allow-Headers", "Content-Type, Authorization"); 
   response.header("Content-Encoding", "UTF-8"); 
});
Spark.get("/infos", (request, response) -> "Connected");

If I enter the IP of my VPS, I get a “failed to bind address” error. Can you help me? THANKS.
