800xA Service Account Management Tool

I followed the procedure described by 3BSE046784-610_A_en_System_800xA_Maintenance to change the 800xAService account password, after the restart all the services come up but I cannot open the "Configure System" in the "System Configuration Console", it just shows "Waiting for connection to local node" as show on the attached pic.

I also realized that the Installer Agent its always disconnected even with the service running.

Does anyone know what could be the issue?

Singlenode - Just with the base installation

Thank you in advance
