When I enable access control connection is lost and I get alarm Legitimation failed, invalid or missing password. I have set user and role, so that I have all rights to HMI. Also password for User and role have been set. Any advice, what I am still missing?

The HMI system's background process handles communication independently of user login. For more details on the connection configuration, please refer to the FAQ. Kind regards Stefan
