Hello. When I try to use SSL mode for FTP (trial team) I cannot see files and I got errors:
[2018/12/28 13:01:49.151] [ERROR ] [ 10528] [SERVICE ] [ nd3 sdk version - child nd3svc : 3.6.571 ] [Child.cpp:132]

Without SSL everything connects normally. Any ideas?

  • found that problem in Active mode. In passive FTPS works. No restrictions between workstation and FTP server

The error number 30 means “FTP PORT operation failed”.
