: Sometimes used as a local endpoint for tools like ngrok or SSH tunnels to forward traffic from a remote deep-learning server to a local browser. Troubleshooting "404" or "Connection Refused"
While localhost usually bypasses firewalls, some strict corporate security policies may block high ports. Temporarily disable the firewall to test, but re-enable it afterward.
http://localhost:11501 represents a local development server bound to port 11501 on your own machine. Since port 11501 has no official IANA assignment, it’s an excellent choice for custom applications, development servers, and testing environments where you want to avoid conflicts with well-known ports.
Who are you? In Chinese.

Just because a service runs on localhost doesn't automatically make it secure. There are important security considerations to keep in mind.
Here’s the step-by-step process:
http POST localhost:11501/items name="Laptop" price:=999.99
Maya leaned closer. The timestamp on the reply read — the exact second she'd hit enter.
No. Port 1151 is in a different range and might be assigned to a different protocol (IETF reserves 1151 for unspecified use). Always use the exact port number. http localhost 11501
Remember: no service, no connection. If you see “connection refused,” start your server. And always keep security in mind—even when working locally.
One of the most concrete uses of port 11501 appears in the context of system administration tutorials. Specifically, there is a guide that covers how to install and configure the MariaDB database server on a CentOS 7 server using this port. If you are following such a tutorial, you might be directed to access your database management interface at http://localhost:11501 . This would be a custom configuration choice made for that specific learning environment.
