You must give LiveSP the URL of the SD-WAN manager (vManage, VSD, FortiManager, etc.), the credentials of an account that LiveSP will use to connect itself to the server and if needed its associated customer. To do this, connect to the LiveSP web UI and login with an admin account; then, in multi-tenant mode, select the Network menu, Provisioning and SD-WAN server library in the scroll input. Then click on New and fill the fields with the correct information and click Import after saving to provision LiveSP once.
