03 Check it

Which program uses port 1122, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1122'      # process listening on 1122
sudo lsof -nP -i :1122

macOS

sudo lsof -nP -i :1122

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1122 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1122
netstat -ano | findstr :1122

From another machine

nmap -p 1122 -sV <host>
sudo nmap -sU -p 1122 <host>
nc -zv <host> 1122
