I get the following error when trying to connect via FTP:
Resolving address of ftpupload.net
Status: Connecting to 127.9.9.9:21…
Status: Connection attempt failed with “ECONNREFUSED - Conexión rechazada por el servidor”.
Error: Could not connect to server.
This is definitely not correct, something on your end, like a firewall, antivirus, or your ISP is manipulating the connection. Try using ftp.epizy.com or the direct IP address 185.27.134.11 to see if it works.
