H32B Pro via Ethernet - no default values in web interface

[Floeckchen]

Dear KinCony Team,

I am trying to use the H32B Pro relay board with Home Assistant via MQTT. First step of the documentation asks to update the firmware.

For that I am following the instructions in the YouTube Video "how to download KC868-H32B Pro firmware by ethernet":

1. The H32B Pro board is plugged into a router. I changed the IP range of the router to allow for 192.168.1.200 and assigned that IP to the H32B Pro. I allowed all ports on that IP.
   
2. My laptop is connected via Wifi to the same router and got the IP 192.168.1.22 (checked via ipconfig)   
   
3. I downloaded the "NET REMOTE IAP" (https://www.kincony.com/forum/attachment.php?aid=1717)
   
4. I downloaded the firmware file (https://www.kincony.com/forum/attachment.php?aid=287), even though I am not sure that is the correct one for the pro board. (a central list of all latest firmware by product would be cool. Did I just not find it?)
   
5. The "try to ping device" works fine. The ping is returned.
   
6. I restart the H32B Pro and click "Connect" within the first 5 seconds of repowering the board. But I get the following error message that I do not understand:
   

   

When I access the board´s IP via Chrome, I can successfully log on to the "net setting", but it does not show any of the values:

   

When I log on "relay control" I can switch the software buttons, but the relays and LEDs on the board do not change.

What am I doing wrong? Help would be much appreciated. Thank you. 谢谢
 
Kind regards
