What (e.g., Node.js , Docker, Python) are you attempting to run on port 11501?
At first glance, localhost11501 can be broken down into two core technical concepts:
If a command line check reveals that a process is already bound to port 11501 , your new application will fail to start. You can terminate the blocking process using its unique Process Identifier (PID). : netstat -ano | findstr :11501 taskkill /PID /F Use code with caution. macOS / Linux : sudo kill -9 Use code with caution. 3. Check Local Firewall Policies
localhost:11501 refers to a network endpoint on your own computer, using port number 11501 . In web development and software testing, localhost is the standard hostname that points to the loopback IP address 127.0.0.1 , meaning the traffic never leaves your machine. localhost11501

In networking, a port is a number used to uniquely identify a transaction over a network by specifying both the host and the service. Ports are 16-bit integers, thus ranging from 0 to 65535.

Now, let's focus on the port number 11501 . In computing, a port is a number assigned to a specific process or service running on a computer. Ports allow multiple applications to share the same IP address, and each port is associated with a particular protocol (e.g., HTTP, FTP, or SSH). Port numbers range from 0 to 65535, with well-known ports (0-1023) reserved for standard services like HTTP (80) and FTP (21).
Accessing http://localhost:11501 would show the NGINX welcome page.
Use your terminal or command prompt to run your application (e.g., kinesalite --port 11501 Verify the URL format: If you are using SSL/HTTPS, ensure you type : netstat -ano | findstr :11501 taskkill /PID
: By default, ensure your server binds strictly to the loopback address 127.0.0.1 rather than your network IP 0.0.0.0 . Binding to 0.0.0.0 could expose your application to anyone sharing your local Wi-Fi or office network.
const express = require('express'); const app = express(); const PORT = 11501; app.get('/', (req, res) => res.send('Localhost 11501 server is active.'); ); app.listen(PORT, () => console.log(`Server running smoothly on http://localhost:$PORT`); ); Use code with caution. Python (Flask)
