Android Question FTP Project - Pruebas

I am using the Pruebas project to try to get FTP working.

Pruebase Project can be found here as a ZIP .. (near bottom of threads)
https://www.b4x.com/android/forum/threads/android-ftp-tutorial.10407/#content (cant attach - says the zipped file is too large)

I get it to compile and run on my Android Phone.
First I tried it as-is - (having checked that the FTP Site and Credentials work using Filezilla - THEY DONT)
Ran it anyway to see what happens - Nothing - No errors - nothing

So then I change the site and credentials to my own FTP Site
I think I have set up my FTP website/Folders etc correctly - which I have been using for years using NCFTP and DOS Batch Files successfully.

When I run the program on my Android phone it gives no errors - nothing

I was hoping at least for some response but am not sure where to put the error messages

============================================================

Before I go any further with Pruebas Project - Is there another example which works that I can download please ? (Pruebas is a download project -I need an upload project)
I am finding lots of code snippets but it would help if I could run something that worked - FTP Client is what I need - To Upload a text file from an Android Phone to my FTP Website

Thanks
