- Close the port if nothing on the host needs it.
- Identify the process that listens on it (commands below) before opening it in a firewall.
- Expose a service only to the networks that use it.

Which program uses port 8043, and is it reachable?
Linux
sudo ss -ltnup 'sport = :8043' # process listening on 8043
sudo lsof -nP -i :8043macOS
sudo lsof -nP -i :8043
Windows (PowerShell)
Get-NetTCPConnection -LocalPort 8043 -State Listen | Select LocalAddress, OwningProcess Get-NetUDPEndpoint -LocalPort 8043 netstat -ano | findstr :8043
From another machine
nmap -p 8043 -sV <host> nc -zv <host> 8043

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 8043 is open?
On Linux run "ss -ltnup 'sport = :8043'", on macOS "lsof -nP -i :8043", and on Windows "netstat -ano | findstr :8043" to see the local process. From another machine, "nmap -p 8043 <host>" shows whether it is reachable.
