Hi.
My server has a issue that made impossible connect on FTP to upload files. This issue cause timeout on listing and uploading... when I look for something on CWP panel is possible see a lot of sessions.

FTP version: 1.0.47
I tried setup passive ports range, open these prots on firewall...
On client side, force plain ftp protocol without encryption.
I had this problem before with customers from firewalled internet (mostly islamic countries).
In filezilla, this setting works:
