LocalTuya Error

I need some help as I have no more ideas.
Whenever I try to add a new device it gives the error that appears in the image.
IP is correct, device ID and local key as well.
I’ve tried to put in the other versions without success.
Does anyone have any more ideas of what it could be?

You have to specify the DP manually, there is a field if you scroll down.
Example metering socket:

You will find many different DP at obove link.
