03 Check it

Which program uses port 7428, and is it reachable?

Linux

sudo ss -ltnup 'sport = :7428'      # process listening on 7428
sudo lsof -nP -i :7428

macOS

sudo lsof -nP -i :7428

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 7428 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 7428
netstat -ano | findstr :7428

From another machine

nmap -p 7428 -sV <host>
sudo nmap -sU -p 7428 <host>
nc -zv <host> 7428

Block it in the firewall

sudo ufw deny 7428/tcp                                         # Linux (ufw)
