Troubleshooting & Helper Box
- Flatpak Sandbox Restrictions (Resources & Mission Center): Flatpaks run in isolated zones. If graphical monitors cannot query host disks or network, run:
flatpak override –filesystem=host net.nokyan.Resources
flatpak override –filesystem=host io.missioncenter.MissionCenter - Enable Cockpit Socket Service: If the Cockpit login screen does not load at `https://localhost:9090`, enable the socket service:
sudo systemctl enable –now cockpit.socket
- Netdata Local Host Access: By default, Netdata is accessible on the local network via port 19999. If it fails to connect, verify your local firewall configuration and allow incoming TCP traffic:
sudo ufw allow 19999/tcp
