The Port Checker Tool is important because it helps you find network problems quickly. Many internet-related issues happen because ports are blocked or misconfigured. Without checking ports, it becomes very hard to find the real cause of the problem. For website owners, an open port is necessary for visitors to access the site. If port 80 or 443 is closed, your website will not load. A Port Checker Tool helps confirm whether these ports are open and working correctly.
