When using FTP from a slow internet connection, files are not fully transferred, and the following error is recorded in the messages log: [INFO] Timeout – try typing a little faster next time
To resolve this, edit pureftpd configuration file:
nano /var/cpanel/conf/pureftpd/main
and add ForcePassiveIP: ~
Save the file, then rebuild configuration:
/usr/local/cpanel/scripts/setupftpserver pure-ftpd --force
