Hi Alexander!
I have tried again from my home and it works. Is it possible that specific network allows only to download files from FTP?
Hello! It seems that file upload to ftp server is broken. I'm using vsftpd in Ubuntu. I can download files, but I can't upload them back. I have tried and experiment and just tried to upload a textastic getting started file and it does not works. I have tried to do it by FTP shell client and uploading works.
