Which program uses port 8202, and is it reachable?
Linux
sudo ss -ltnup 'sport = :8202' # process listening on 8202
sudo lsof -nP -i :8202macOS
sudo lsof -nP -i :8202
Windows (PowerShell)

From another machine
nmap -p 8202 -sV <host> sudo nmap -sU -p 8202 <host> nc -zv <host> 8202
Block it in the firewall

What is port 8202 used for?

Port 8202 is registered for UDP.
Is it safe to open port 8202?
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. Require authentication on cameras and media servers.
How do I check if port 8202 is open?
On Linux run "ss -ltnup 'sport = :8202'", on macOS "lsof -nP -i :8202", and on Windows "netstat -ano | findstr :8202" to see the local process. From another machine, "nmap -p 8202 <host>" shows whether it is reachable.
