i have error when i tried to add
Nom d’hôte has to be unique per provider type

validate " ok"
add " no"

Just remove the duplicate Kubernetes provider you already have - hence the warning that you’re trying to add a provider with the same hostname & type you already have.

in the dashbord i dont have any provider container

That is very strange…I wonder if some child manager is having duplicate names? Can you check the ext_management_systems and providers tables in the database and see what is there (in particular the names)?
