- Plesk for Windows
Unable to upload/download/list files using passive FTP mode:
[root@jumper ~]# ftp example.com
227 Entering Passive Mode (203,0,113,2,255,220).
ftp: connect: Connection refused
This is Plesk bug with ID #PPPM-5216 which is planned to be fixed in future Plesk updates.
As a workaround, set External IP Address of Firewall in IIS for each FTP site manually under IIS > Sites > <IP_address> > FTP Firewall Support.
