A8 Ethernet strange malfunction

[bogdan_0]

Hello

Wired ethernet is not functioning properly.
Via usb cable it is responding but webpage (KCS) usually can not be displayed (it worked a few times but most of times it does not work):
"This site can not be reached"
ESPhome integration in HA via ethernet is generally offline.
I tried reset and new set-up of UDP connection settings.
I tried upgrade of firmware and then reset and new set-up. 

Can you please help?
Thank you
Bogdan

you can download KCS v2 firmware to test your PCB hardware.
after download firmware, re power on of your board. the board will work in DHCP mode as default. Then you can use kincony scan device tool to find out the IP address of KC868-A8.
