This error message means that no device on the network has responded to the name that you have entered. A common problem is to enter more than just the network name or IP address. A Share name or Folder name is not needed at this stage.
If you want to get connected as quickly as possible, use an IP address instead of a network name. You can return to this page later to try the network name once you know that FileBrowser will connect.
