I have a program that constantly monitors a server, connecting with FTP mode "Pasive" through the port 21. It works fine until the server is restarted, when this event occurs, the application simply stop it's process. It doesn't throw any error, or timeout, and the log doesn't register anything.
On the server side, the server is running at 10% of it's process power and the RAM Memory it's at 45%.
Greetings and thank you for your attention.
