03 Check it

Which program uses port 1145, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1145'      # process listening on 1145
sudo lsof -nP -i :1145

macOS

sudo lsof -nP -i :1145

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1145 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1145
netstat -ano | findstr :1145

From another machine

nmap -p 1145 -sV <host>
sudo nmap -sU -p 1145 <host>
nc -zv <host> 1145

Block it in the firewall

sudo ufw deny 1145/tcp                                         # Linux (ufw)
