# Error loading config file
You may encounter errors loading the config file on POSIX operating systems if:
- an unauthorized user tries to load the config file, or
- the config file has the wrong permissions.

See [Config File Ownership and Permissions](https://www.elastic.co/docs/reference/beats/libbeat/config-file-permissions) for more about resolving these errors.
