Security guidance

Use 2083 (TLS) instead, and restrict by IP if your host allows it.

Test port 2082 yourself

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

macOS / Linux — netcat

nc -vz example.com 2082

Any OS — nmap

nmap -p 2082 example.com

Windows — PowerShell

Test-NetConnection example.com -Port 2082

open = a service answered on port 2082; 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.
