Last year my team made an online boardgame for school. The frontend is html/css and JS. The backend is an ASP .net Core app. The frontend is already set up on my server using NGINX. I wanted to host it on my portfolio site but the structure of the backend was provided to us by the teachers (i have gotten permission to host it) so it's not completely clear to me how exactly I should alter the code in order for the API to communicate properly with the frontend.The API was originally running on localhost.

What I do know is that I need an ARM Linux build to be able to run it on the server I have. I am assuming that in the launchsettings.json I need to alter the applicationUrl from localhost:5000 and localhost:5001 to something else and then match the code in the frontend to that address but i'm unsure where it should point to.

Should it be the domain name that points to my server? Or am I missing something?

This is literally my first question here so sorry if it's not in the proper format or unclear.

The code for the launchSettings.json for the API

{
  "$schema": "http://json.schemastore.org/launchsettings.json",
  "iisSettings": {
    "windowsAuthentication": false,
    "anonymousAuthentication": true,
    "iisExpress": {
      "applicationUrl": "http://localhost:53518",
      "sslPort": 44307
    }
  },
  "profiles": {
    "Stratego.Api": {
      "commandName": "Project",
      "launchBrowser": false,
      "launchUrl": "swagger",
      "applicationUrl": "https://localhost:5001;http://localhost:5000",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      }
    }
  }
}

An example of a request in the frontend

get('https://localhost:5001/api/Game/' + localStorage.getItem("gameId") + '/board', headers)
        .then(response => {
            response.text().then(async function (message) {
                let parsed = JSON.parse(message);
                if (!containsBoard()) {
                    createBoard(parsed.squares, parsed.size);
                }
            });
        });
