You may see a ‘List Error’ in your share. This can mean a few things, the next step to diagnose it to look at your connector logs (see Windows, Linux). You should also look at your connector overview in https://admin.__MYDOMAIN__/ under resources/connectors/overview.

Different reasons:

• The connector may be missing OS-level permission to read the underlying files
• The share directory may be missing.
• You may have fine-grained permissions enabled and the user does not have permission (e.g. is not on your domain, or, NTFS permissions restrict).
