I can't join my nas to my active directory domain

Hi,
I need help i use a raspberry p3 model b+ to set up an active directory domain, but when i try to connect my nas to my domain.
I entered all the requested data, the page gives the update alert but when it is updated everything remains unchanged. the fields remain filled and it doesn’t keep me going
