03 Check it

Which program uses port 2926, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2926'      # process listening on 2926
sudo lsof -nP -i :2926

macOS

sudo lsof -nP -i :2926

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2926 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2926
netstat -ano | findstr :2926

From another machine

nmap -p 2926 -sV <host>
sudo nmap -sU -p 2926 <host>
nc -zv <host> 2926

Block it in the firewall

sudo ufw deny 2926/tcp                                         # Linux (ufw)
