ASP.Net Core AxiosError: Network Error

I've deployed an ASP.Net Core with react project to somee.com, the frontend loads just fine but axios.get is returning this:

{
    "message": "Network Error",
    "name": "AxiosError",
    "stack": "AxiosError: Network Error\n    at l.onerror (http://something.somee.com/static/js/main.17849c8f.js:2:700322)",
    "config": {
        "transitional": {
            "silentJSONParsing": true,
            "forcedJSONParsing": true,
            "clarifyTimeoutError": false
        },
        "adapter": [
            "xhr",
            "http"
        ],
        "transformRequest": [
            null
        ],
        "transformResponse": [
            null
        ],
        "timeout": 0,
        "xsrfCookieName": "XSRF-TOKEN",
        "xsrfHeaderName": "X-XSRF-TOKEN",
        "maxContentLength": -1,
        "maxBodyLength": -1,
        "env": {},
        "headers": {
            "Accept": "application/json, text/plain, */*"
        },
        "method": "get",
        "url": "http://something.somee.com:5030/api/user/null"
    },
    "code": "ERR_NETWORK",
    "status": null
}

I did the following to ensure the endpoint is setup correctly for every axios request: 

const apiUrl = process.env.REACT_APP_API_URL;
const response = await axios.get(`${apiUrl}/user/taskss/${params.id}`);

with the .env file being: 

REACT_APP_API_URL=http://something.somee.com:5030

I also did this on appsettings.js: 

"Kestrel": {
    "Endpoints": {
      "Http": {
        "Url": "http://something.somee.com:5030"
      }
    }
  },

And the Program.cs: 

var hostBuilder = WebHost.CreateDefaultBuilder(args);

// Set the listening URL using the UseUrls method
hostBuilder.UseUrls("http://something.somee.com:5030");

var app = builder.Build();

// Enable CORS
app.UseCors(options => options
    .AllowAnyOrigin()
    .AllowAnyHeader()
    .AllowAnyMethod()
);
