Plutonium

Try this fix for windows:
Go to the start menu and type in "Windows Defender Firewall"
On the sidebar click "Advanced settings"
Click "Inbound Rules" and scroll down to "plutonium-bootstrapper-win32.exe" (i had two of them)
For each of them Right click -> Properties then go to "Protocols and Ports" and change the "Protocol type" to "Any", then go to "Advanced" and under "Edge traversal" change the option to "Allow edge traversal"
