Hi Folks,

* Restart systemd service

* Failed to register mondoo package for cnquery and cnspec. Please reach out in the Mondoo Community GitHub Discussions - https://github.com/orgs/mondoohq/discussions.

Hi @PeterBarczi,

are you using automation to deploy the package to your fleet? Can we exclude an invalid registration token as the possible cause?

Hi @philipbalinov thnx, i tried to properly uninstall it and install it anew but unfortunately still the same.. I've used installation script, so not sure what is wrong with that..

Hi @philipbalinov I find the root cause, it is in ntp not synced. after enabling ntp synchronization installation worked properly! thnx for reaction and willingness to help. All good for now. thnx
