Issue/Introduction

We cannot access the GUI and cannot turn the service on.

Starting controlcenter (via systemctl):  Job for controlcenter.service failed because the control process exited with error code. See "systemctl status controlcenter.service" and "journalctl -xe" for details.

Resolution

Determine if the old Control Center has not pushed the update to your asset, causing the setup to be overwritten.

For instance, in the past role 3 has been assigned and out of sudden You noticed role 1.

In a such case, redeploy the system and ensure that communication on port 41002 will be allowed back on forth only for the assets given in the SMG inventory.
