FTP error ECONNABORTED – Conection aborted

This post is also available in: Slovenian

When I recently try to upload files to an FTP server my FTP client give me alert ECONNABORTED – Connection aborted.

142j1SOK-filezilla[1]When I look to log file, loging was ok without problems, however, it is stuck on uploading. Even a change to the less secure password-free and TLS does not help, nor a change the active/pasive mode and file has ASCII characters.

It was a mistake on the enterprise firewall, where it was deactivated FTP upload. With the opening of this Protocol on the firewall, uploads begin.

I use free ftp client FileZilla in wehre I recommend to manually configure the logging for quicker founding solution.
