Videos won't play, getting error

I have installed XBMC to my iPad 2 to stream videos through https from my seedbox. I managed to play 1 video (.avi) successfully but I am having problems with other videos.

I am trying to get logs but I can't. I tried instructions from http://wiki.xbmc.org/index.php?title=HOW...og_for_iOS but I can't connect to it using FileZilla. I get "Network error: Connection refused" message.
