切换 Selenium 模式后不能获取元素

从 Appium 模式切换到 Selenium 模式不能找到元素信息

    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
    if (driver.isAppInstalled("com.pingan.fpm") && driver.findElement(By.name("登录")).isDisplayed()) {
        driver.findElement(By.name("登录")).click();
    }
    if(driver.findElement(By.linkText("用户名不能为空")).isDisplayed()) {
        System.out.println("TestCase运行成功");
    }
}

在 Appium 模式下可以获取到登录按钮的，切换 Selenium 后不能识别，给了 Selenium 端口号，还需要在 Appium 上配置什么吗？
错误信息如下

org.openqa.selenium.NoSuchElementException: An element could not be located on the page using the given search parameters. (WARNING: The server did not provide any stacktrace information)
