Synology NAS

Synology NAS: A data write error occurred while generating the usage report.

This happens only when the NAS is connected to domain with multiple domains in the forest and after the upgrade to DSM version 7.1. The default Management Mode setting is “Trusted Domains” with all domains in the forest selected. To resolve the issue with the reports, change this setting to “Single Domain with OUs”.

Go to Control Panel -> Domain/LDAP and click the Edit button. From the drop-down, select “Single domain with OUs” and click the Save button

Synology Drive App for Windows 10 does not connect

When trying to connect, the app displays a message:

Connection fail. Check your network settings and try again.

The solution to this is that next to port 5000 and 5001, the port 6690 also has to be opened to the Synology NAS. If this port is not opened, the Windows app will fail.

The Android and iOS apps will work with just port 5000 (or 5001 if SSL is selected and the certificate is valid).
