Hi @alberto77,

Based on the screenshot, more likely the problem is more related to the application layer, as you could access the switch. I assume that the firewall inbound rule is blocking the FTP service.

For a simple test, you may disable the PC firewall and wait for a bit and reconnect to switch via FTP. 
Reminder: It might need a minute to reconnect again as the session needs to finish the traffic flow.

After disabling the firewall, please try to "get config" again for verification.

Tips: You may also add an allow inbound rule in the firewall settings if you don't want to disable the whole firewall application.

Steps as figure below:

Hope it helps.
