Here’s a blog post tailored to your request. Since “https localhost:11501” with a 2021 context likely refers to running a local secure web server (e.g., for development, testing, or a specific tool), I’ve written a general, informative post that explains what this means, why HTTPS on localhost matters, and how to troubleshoot common issues.
netstat -aon | findstr :11501
lsof -i :11501
Solution: Add an exception or change the port (e.g., 11502). https localhost11501 2021
A: Not inherently. It’s just a number. However, if you didn’t start a server on that port, it could be malware or a forgotten dev tool. Always check with netstat or lsof. Here’s a blog post tailored to your request
Host: localhost - This refers to the local machine. When you use localhost in a URL, you're essentially referring to your own computer as the server. This is commonly used during web development to test websites or web applications locally before making them live on the internet. Windows (Command Prompt) :
netstat -aon | findstr :11501
https.createServer(options, (req, res) => if (req.url === '/2021') res.writeHead(200, 'Content-Type': 'text/html' ); res.end('<h1>Welcome to the 2021 local project</h1>'); else res.writeHead(404); res.end();
