Port 2083 — cPanel (TLS)

Security guidance

Acceptable, but a login panel exposed to the world will be brute-forced. Use strong passwords and two-factor authentication.

Test port 2083 yourself

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

macOS / Linux — netcat

nc -vz example.com 2083

Any OS — nmap

nmap -p 2083 example.com

Windows — PowerShell

Test-NetConnection example.com -Port 2083

open = a service answered on port 2083; 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.
