03 Check it

Which program uses port 2678, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2678'      # process listening on 2678
sudo lsof -nP -i :2678

macOS

sudo lsof -nP -i :2678

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2678 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2678
netstat -ano | findstr :2678

From another machine

nmap -p 2678 -sV <host>
sudo nmap -sU -p 2678 <host>
nc -zv <host> 2678
