Integration issue: LEGRAND HOME PLUS

when trying to add LEGRAND HOME PLUS (ha core 2021.4.3) I get redirected to a web page showing the error below:

“error”: “invalid_request”,
“error_description”: “The reply url host homeassistant.local doesn’t match with the ones configured on the application”

Is there someone knowing why it is giving that error?

Thank you in advance.

I have exactly the same problem… I don’t know if I have to create a reverse proxy entry, or something like that, a the error box says that my local IP is not the address implemented for my application.
I don’t find what to do …
