03 Check it

Which program uses port 3027, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3027'      # process listening on 3027
sudo lsof -nP -i :3027

macOS

sudo lsof -nP -i :3027

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3027 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3027
netstat -ano | findstr :3027

From another machine

nmap -p 3027 -sV <host>
sudo nmap -sU -p 3027 <host>
nc -zv <host> 3027

Block it in the firewall

On Linux run "ss -ltnup 'sport = :3027'", on macOS "lsof -nP -i :3027", and on Windows "netstat -ano | findstr :3027" to see the local process. From another machine, "nmap -p 3027 <host>" shows whether it is reachable.
