03 Check it

Which program uses port 3574, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3574'      # process listening on 3574
sudo lsof -nP -i :3574

macOS

sudo lsof -nP -i :3574

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3574 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3574
netstat -ano | findstr :3574

From another machine

nmap -p 3574 -sV <host>
sudo nmap -sU -p 3574 <host>
nc -zv <host> 3574

Block it in the firewall

sudo ufw deny 3574/tcp                                         # Linux (ufw)

It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Close the port if nothing on the host needs it.

How do I check if port 3574 is open?

On Linux run "ss -ltnup 'sport = :3574'", on macOS "lsof -nP -i :3574", and on Windows "netstat -ano | findstr :3574" to see the local process. From another machine, "nmap -p 3574 <host>" shows whether it is reachable.
