Many development servers run on random high-numbered ports. For example:
If a developer in 2021 configured a project to run HTTPS on port 11501, the command might have been: https localhost11501 2021
ng serve --port 11501 --ssl

It looks cryptic – a mix of a secure protocol, a familiar hostname, and an unusual port number. In 2021, this pattern became increasingly common as developers embraced local HTTPS for parity with production environments. Many development servers run on random high-numbered ports
But what exactly is https://localhost:11501? Why does it matter? And why 2021 specifically? Let’s break it down. If a developer in 2021 configured a project
Solution: Add an exception or change the port (e.g., 11502).
