Relution Update from 4.79 to 5.x not woring

This week I have updated the UCS server instance to 5.0-2. First step worked fine and Relution App 4.79.8 is still working. After that I updated Relution App to version 5.14.1. The UCS server rebooted correctly but I was not able to open UCS management console or connect to relution app.
Checking Apache Status with “systemctl status apache2.service” it throw an error message: Active: failed (Result: exit-code).
Any help available?
