Un Functional Tests using a Headless Browser, can't pass

Tell us what’s happening:
in Repl.it, My code appears to be passing the challenge in the terminal, but not when I submit to freecodecamp. Alternatively, when I try to run it locally on VSCode, it wont pass in the terminal nor on freecodecamp. I think it doesn’t like the line Browser.localhost('example.com, process.env.PORT || 3000); is broken. Am I doing some

Your code so far
Heres a snippet, I’ve tried different values for Broswer.site

const Browser = require("zombie");
Browser.site = 'https://boilerplate-mochachai-2.jacklmbrt07.repl.co';

suite("e2e Testing with Zombie.js", function () {
  const browser = new Browser();

  suiteSetup(function(done) {
    return browser.visit('/', done);

  suite('"Famous Italian Explorers" form', function () {
    // #5
    test('submit "surname" : "Colombo" - write your e2e test...', function (done) {
      browser.fill("surname", "Colombo").pressButton("submit", function () {
        browser.assert.text('span#name', 'Cristoforo');
        browser.assert.text('span#surname', 'Colombo');
        browser.assert.element('span#dates', 1);

Again, this passes in the Repl.it terminal but not on the fcc submission for challenge 23/25. Am I doing something wrong or is FCC wrong?
