Understanding HTTPS, Localhost, Port 11501, and Legacy Systems Seeing localhost:11501 in logs or trying to access
This combination—a secure protocol on a non-standard port—is most commonly encountered in the context of local software development, testing, or debugging. A web or application developer might have configured their local server to run on port 11501 with HTTPS enabled. Seeing localhost:11501 in logs or trying to access https://localhost:11501 in a browser would be a typical part of that workflow.
Localhost 8080 refers to accessing a web service running on your own computer through port 8080, a commonly used HTTP development ... to a developer or system administrator

To the uninitiated, this string looks like an error or a broken link. However, to a developer or system administrator, it represents a specific instruction set for a local machine. Let’s break down the anatomy of this URL and explore what it actually does.
You would typically encounter https://localhost:11501/2021 in the following scenarios:
On Mac/Linux (Terminal): Run lsof -i :11501 to find the PID, then kill it using kill -9 .
