Verify if sharktankblog.com is displaying its actual blog content. If it is, identify and list all primary navigation categories or sections visible on the homepage. If the website is not displaying its blog content (e.g., showing a server error or a default page), state that the content is inaccessible and the task cannot proceed.
Navigate to 'http://sharktankblog.com/'. Observe the content displayed on the page. If the actual blog content is visible, identify and list all main navigation categories or sections displayed on the homepage. If the website is not displaying its blog content (e.g., showing an Nginx welcome page, a 404 error, or any other non-blog content), explicitly state this observation and conclude that the task cannot be completed.
The agent successfully navigates to 'http://sharktankblog.com/'. If the actual blog content is displayed, the agent lists the main content categories or navigation links found on the homepage (e.g., 'Home', 'About', 'Contact', 'Categories', 'Updates', etc.). If the website is not displaying its blog content (e.g., showing the Nginx welcome page as observed in the trajectory), the agent explicitly states that the blog content is inaccessible and therefore the task of identifying navigation categories cannot be completed.
