Set ON/OFF one channel of digital output

[kloper360]

I just got my boards and wanted to test the HTTP GET SET commands to read or set the IOs, but somehow I am not abel to do it. 
Hope somebody here can help me find the issue.

I got this documentation: https://www.kincony.com/forum/attachment.php?aid=2871
It explains clearly what commands to use. 
For example: http://192.168.1.200/ctrl.cgi?secret=abc...=1&value=1
This should set the Output1 to HIGH, but I its not and I am getting the messege in the browser: {"code":-2,"status":"http not open"}

According to the documentation I need to set the "secret" in the board settings, but I cant find that field anywhere.
I am using version: v2.2.2

I can access the board over the IP, I can monitor IOs and I can set them manually to high or low... its only that my HTTP request command doesnt do it.

The other issue is, I cant seem to trigger digital input... atleast its never showing green in the monitor page. I tryed to apply 12V and 24V to it, but nothing is registered. Do digital inputs need to be activated somehow first?

I am using a 24V power supply to digital input ground and pin1.

Thanks in advanced!
