If the Desktop Sync client connects to Alfresco Content Services to start content selection then immediately goes offline, folders may already have been created, but no files have been synced; check the following:

  • The Sync Service is running
  • The Sync Service is accessible from the client - you can use the Healthcheck URL in the clients browser
  • The global properties file is correctly set up - see Install Sync Service

For example, if the Sync Service port is not open on the firewall, then the client won't be able to connect to the Desktop Sync service, or the Healthcheck URL. The port is set when installing the Sync Service, where the default is 9090.

Note

Desktop Sync 1.2 (for Windows and Mac) performs a health check which prevents this from occurring.
