I use OH 4.0.4 and the hue binding.
Also i use (https://diyhue.github.io/) as hue emulation. Diyhue runs in Docker with the host network mode. Diyhue also works flawlessly with the hue app and also hue essentials. Only OH4 does not want to.
Unfortunately, I cannot use the binding because I get the error message
“An unexpected exception occurred: Error opening HTTP/2 session → java.io.IOException: Broken pipe”
immediately after entering the IP address.
