HtmlUnit: Find driver by classname doesnt work with HtmlUnit but works with Chrome

[danielkp1234]

So i am having another problem trying to click a button with htmlunit driver it works with the chrome driver here is the code i am trying to use
` driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
driver.get("https://frostruphave.viggo.dk/Basic/Account/Login");

System.out.println(driver.getPageSource());

WebDriverWait wait = new WebDriverWait(driver, 8);

wait.until(ExpectedConditions.visibilityOfElementLocated(By.className("unic")));

driver.findElement(By.className("unic")).click();`

The line that causes the problem is wait.until(ExpectedConditions.visibilityOfElementLocated(By.className("unic")));
