Error connecting Hue Essentials or any other Android app

[cibrenvenuti]

As by title, Hue Essentials give me a "Missing config field when I try to connect to the bridge"

This is the response from the author of the App:
"Hi, there appears to be an issue with your diyHue configuration. In the response the config field is missing, which is not something I can fix. Please report this issue to diyHue or check the configuration yourself. Let me know if you have any questions."
But my config is well populated and formatted...
Moreover some lights seems unreachable in DIYhue. It happens every now and then, even if I can reach them trough HA and Z2M.

What can I do?
Thanks in advance for your help.

PS: I had already written in response to another topic, but the error I have is different, so I thought of opening a new issue.

I have this same issue as well

Unfortunally, seems that there is no interest to solve this issue
