# Troubleshooting And Log Files

## Troubleshoot Image Library issues

If the Service Health dashboard shows that the image library service is unhealthy, the issue may be caused by one of the following:

* You do not have certificate authorization to access the image library service.
* The image library service is not responding on one or more hosts configured with the image library role.

To debug the issue, check the log files on the affected hosts.

### Log files

The image library service logs are located at:

`/var/log/pf9/glance-api.log`
