Actually there aretwo inputelements present with the same name usernamewhere one is hidden and another is visible and you are intracting with first one which is not visible on the page that's why you are unable to locate, try using cssSelectoras below :-
实际上，存在两个input具有相同名称的元素，username其中一个是隐藏的，另一个是可见的，并且您正在与第一个在页面上不可见的元素相提并论，这就是您无法找到的原因，请尝试cssSelector如下使用：-
WebDriverWait wait = new WebDriverWait(driver,30);
WebElement element = wait.until(ExpectedConditions.visibilityOfElementLocated(By.cssSelector("div#load_box input[name = 'username']")));
element.sendKeys("john");
