03 Check it

Which program uses port 1778, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1778'      # process listening on 1778
sudo lsof -nP -i :1778

macOS

sudo lsof -nP -i :1778

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1778 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1778
netstat -ano | findstr :1778

From another machine

nmap -p 1778 -sV <host>
sudo nmap -sU -p 1778 <host>
nc -zv <host> 1778

Block it in the firewall

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 1778 is open?

On Linux run "ss -ltnup 'sport = :1778'", on macOS "lsof -nP -i :1778", and on Windows "netstat -ano | findstr :1778" to see the local process. From another machine, "nmap -p 1778 <host>" shows whether it is reachable.
