`lftp` does not connect to FTPS (ftp over ssl)

I have trouble in connecting lftp with **ftps** (ftp over ssl, not sftp!) server ([FTP Server Ultimate](https://play.google.com/store/apps/details?id=com.icecoldapps.ftpserverultimate) ([PRO](https://play.google.com/store/apps/details?id=com.icecoldapps.ftpserverultimatepro) version).) running on Android phone. Technical details: Linux part. Following : https://superuser.com/questions/623236/simple-command-to-connect-to-ftps-server-on-linux-command-line I’ve created following lftp_config file and source it in following way: $ cat lftps_config user photos PASSWORD set ftps:initial-prot ""; set ftp:ssl-force true; set ftp:ssl-protect-data true; set ssl:verify-certificate no; open ftps://192.168.1.103:43210 $ lftp lftp :~> source lftps_config lftp 192.168.1.103:~> dir ls at 0 [530 Login incorrect.] while on “FTP Server Ultimate Pro” logs I see: 2015-10-18 10:10:13 [photosXYZ] - 192.168.1.123 (JBTTAX) - "" and *** are not allowed combination... 2015-10-18 10:10:13 [photosXYZ] - 192.168.1.123 (JBTTAX) New connection... Could you help me how to setup FTP over SSL (ftps) connection on Linux using lftp (or other command-line tool with good mirror capability) ? FTR, I use: $ lftp -v | tail -n 1 Libraries used: Readline 6.3, Expat 2.1.0, GnuTLS 3.4.5, zlib 1.2.8 which according to documentation has FTPS capability (GnuTLS implies it). For curious, more context: My final goal: Have some directories automatically backed up (both, locally and remotely) from my Android phone to Linux workstation, laptop etc. * Android: FTPS server (ftp over ssl, not sftp!), starting automatically when I enter my home wifi, when away using DDNS (Dynamic DNS) * Linux: lftp (or other command line tool) that backs up stuff from phone - might be triggered by some cron-like automation that in presence of my phone ftps server would trigger automatic backup Android part I (as least I thought, that I) solved with [FTP Server Ultimate](https://play.google.com/store/apps/details?id=com.icecoldapps.ftpserverultimate) (to be specific [PRO](https://play.google.com/store/apps/details?id=com.icecoldapps.ftpserverultimatepro) version). Server has capability of running FTPS server, and starting it automatically on given SSID or BSSID. When I am travelling it can update DDNS automatically, what makes reachability from my home servers easy.
