QUESTION

Why is FTP or an Ebuddy operation failing for my Ewon after firmware 15.0s1 (Flexy) or 23.0s1 (Cosy+).

 

ANSWER

A common failure after firmware 15.0s1 (Flexy) or 23.0s1 (Cosy+) is due to FTP now being closed on all interfaces by default.

 

To generate a backup you can alternatively use the web interface:

If you'd like to enable FTP, modify the "ClosedDevice" parameter as shown below. A value of zero will open FTP on all interfaces. The default value of 21 will disable FTP on all interfaces. More info about this parameter can be found here:

Be sure to save and reboot for this change to take effect.
