why do I get 403 error with GraphDB when I use a different PC?

Question

I was following this package tutorial for connecting to GraphDB. It worked. But then, I am now running the same code on a different PC and I get 403 Error... I don't understand why it used to work on one pc and now not on the other one? In the end, I use the graphDBEndpoint module to use it for the query.js.

This is my code:

const { EnapsoGraphDBClient } = require("@innotrade/enapso-graphdb-client");
const { EnapsoGraphDBAdmin } = require("@innotrade/enapso-graphdb-admin");

// connection data to the running GraphDB instance
const GRAPHDB_BASE_URL = "http://127.0.0.1:7200",
  GRAPHDB_REPOSITORY = "Test",
  GRAPHDB_USERNAME = "Test",
  GRAPHDB_PASSWORD = "Test",
  GRAPHDB_CONTEXT_TEST = "http://ont.enapso.com/repo",
  GRAPHDB_CONTEXT_SHACL = "http://rdf4j.org/schema/rdf4j#SHACLShapeGraph";

const DEFAULT_PREFIXES = [
  EnapsoGraphDBClient.PREFIX_OWL,
  EnapsoGraphDBClient.PREFIX_RDF,
  EnapsoGraphDBClient.PREFIX_RDFS,
  EnapsoGraphDBClient.PREFIX_XSD,
  EnapsoGraphDBClient.PREFIX_PROTONS,
  {
    prefix: "entest",
    iri: "http://ont.enapso.com/test#",
  },
];

let graphDBEndpoint = new EnapsoGraphDBClient.Endpoint({
  baseURL: GRAPHDB_BASE_URL,
  repository: GRAPHDB_REPOSITORY,
  prefixes: DEFAULT_PREFIXES,
  transform: "toJSON",
});

graphDBEndpoint
  .login(GRAPHDB_USERNAME, GRAPHDB_PASSWORD)
  .then((result) => {
    console.log(result);
  })
  .catch((err) => {
    console.log(err);
  });

exports.uploadFiletoGraphDB = (filePath) => {
  graphDBEndpoint
    .uploadFromFile({
      filename: `./${filePath}`,
      format: "application/rdf+xml",
      baseIRI: "http://ont.enapso.com/test#",
      context: "http://ont.enapso.com/test",
    })
    .then((result) => {
      console.log(result);
    })
    .catch((err) => {
      console.log(err, "process error here...");
    });
};

exports.getQuery = async (queryString) => {
  return new Promise(function (resolve, reject) {
    graphDBEndpoint
      .query(queryString, {
        transform: "toJSON",
      })
      .then((result) => {
        resolve(result);
      })
      .catch((err) => {
        reject(err);
      });
  });
};
exports.GRAPHDB_CONTEXT_TEST = GRAPHDB_CONTEXT_TEST;

exports.module = graphDBEndpoint;```
