Error code: 409 appears on Acer notebooks because Acer Always Connect is incompatible with your current network connection.
Workaround: When using Acer Always Connect, your AcerCloud computer must be connected to a secure network . If it's connected to a public network, change it to a private (home or work) network. If it's connected to a private (home or work) network and you receive this error message, this may be caused by a connection issue at your current location. Please wait for a while and try again.
