03 Check it

Which program uses port 2964, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2964'      # process listening on 2964
sudo lsof -nP -i :2964

macOS

sudo lsof -nP -i :2964

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2964 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2964
netstat -ano | findstr :2964

From another machine

nmap -p 2964 -sV <host>
sudo nmap -sU -p 2964 <host>
nc -zv <host> 2964

Block it in the firewall

sudo ufw deny 2964/tcp                                         # Linux (ufw)
