03 Check it

Which program uses port 1670, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1670'      # process listening on 1670
sudo lsof -nP -i :1670

macOS

sudo lsof -nP -i :1670

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1670 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1670
netstat -ano | findstr :1670

From another machine

nmap -p 1670 -sV <host>
sudo nmap -sU -p 1670 <host>
nc -zv <host> 1670
