Seeing it on your PC

A listener on 8080 is usually a development server, a proxy or an app's built-in web interface.

Should you block it?

Find which program owns it. Development servers should listen on 127.0.0.1 only.

Check it on your PC

Run this in PowerShell to see what is using port 8080 right now, and which program owns it:

Get-NetTCPConnection -LocalPort 8080 -ErrorAction SilentlyContinue | Select-Object LocalAddress,LocalPort,RemoteAddress,RemotePort,State,@{n='Process';e={(Get-Process -Id $_.OwningProcess -ErrorAction SilentlyContinue).ProcessName}}

No output means nothing is using the port at the moment. For every connection at once, paste netstat -ano into the netstat explainer.

Block it in Windows Firewall

In PowerShell run as administrator, this stops other computers from connecting to this port on your PC. It does not stop your own programs connecting out.

New-NetFirewallRule -DisplayName "Block inbound TCP 8080" -Direction Inbound -Protocol TCP -LocalPort 8080 -Action Block

Undo it with Remove-NetFirewallRule -DisplayName "Block inbound …", using the same name. If you depend on the service on your local network, this rule stops that too.
