Linux Native v0.10.3
a minor one

Error getting thrown in journalctl when acme.json exists, but is empty.

populating acme.json with generic data resolved the error. This would only persist on fresh installs without certs, or installs using custom certs.

further testing revealed that simply placing {} in the acme.json resolved the error, no need to populate the file further on a clean install of traefik && traefik-manager.
