Port 8080 — HTTP alternate

Security guidance

Frequently an unprotected admin panel. Know exactly what is listening before leaving it open.

Test port 8080 yourself

From your own machine, against any host (swap in your domain):

macOS / Linux — netcat

nc -vz example.com 8080

Any OS — nmap

nmap -p 8080 example.com

Windows — PowerShell

Test-NetConnection example.com -Port 8080

open = a service answered on port 8080; closed = the host replied but nothing is listening; filtered = a firewall silently dropped the probe. These test from your network — our port checker tests from the outside, the view that matters for security.
