CDP Public Cloud :Nifi Insufficient Permissions

Hi folks, 

We've just install CDP Public Cloud over Azure and we are working with data hubs cluster. We have a brand new environment and data hubs. 

We are unable to access to Nifi UI with any user except the account owner. 

The users have privileges in the environment(EnvironmentUser) and also in the data hub (DHUser)

What should I do next? is this related with ranger?

Thanks in advance
