Hi,
When Secure FTP option is set to FTPS in Admin Backup/Transfer the backup fail with an error "FTP information invalid", When Secure FTP option is set to NO, the backup is working like it should be.
Here is the ftp server log for secure connection:

As you can see, In FTPS (TLS) connection it's have a strange behavior, it's start with entering to EPSV mode and then to PASV mode, and finally - get stuck.
I've verified that it's not a ftp server side problem, I can connect and upload files with filezilla / flashfxp clients.

Any help will be very appreciated!
