03 Check it

Which program uses port 18262, and is it reachable?

Linux

sudo ss -ltnup 'sport = :18262'      # process listening on 18262
sudo lsof -nP -i :18262

sudo lsof -nP -i :18262

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 18262 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 18262
netstat -ano | findstr :18262

From another machine

nmap -p 18262 -sV <host>
sudo nmap -sU -p 18262 <host>
nc -zv <host> 18262

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 18262 is open?

On Linux run "ss -ltnup 'sport = :18262'", on macOS "lsof -nP -i :18262", and on Windows "netstat -ano | findstr :18262" to see the local process. From another machine, "nmap -p 18262 <host>" shows whether it is reachable.
