03 Check it

Which program uses port 3995, and is it reachable?

Linux

sudo ss -ltnup 'sport = :3995'      # process listening on 3995
sudo lsof -nP -i :3995

macOS

sudo lsof -nP -i :3995

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 3995 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 3995
netstat -ano | findstr :3995

From another machine

nmap -p 3995 -sV <host>
sudo nmap -sU -p 3995 <host>
nc -zv <host> 3995
