I cannot access FTP using Filezilla as I keep getting the error:
Connection attempt failed with “ECONNREFUSED - Connection refused by server”.
Ubuntu 20.04, Vultr VPS
According to our network scan, port 21 is closed, which indicates that there isn’t a listening service on that port. Did you install an FTP server?
Firewall rule says:
FTP tcp 0.0.0.0/0 21
What am I missing?
