[J_Xia]

Description	This article describes that when registering FortiAPs and FortiSwitches to FortiCloud via the FortiGate GUI after 'right-clicking' on the device, it shows as 'offline', and the registration button is grayed out. ' The device cannot be registered from the CLI either, and it displays the following error message: 'FAP/FSW: FP431Fxxxxxxxxxx is NOT connected', Command: diagnose forticare direct-registration product-registration -N S124DP3X15000000 -a xxxx@fortinet.com -p LDAP -T "CA" -R "other" -e 1 Debug logs for 'Forticldd; do not show anything related to device registration when registering the device via the CLI. However, the GUI and the CLI 'get wireless-controller wtp-status' both indicate that the FortiAP is connected to the FortiGate for management and yet the direct-registration still does not work.
Scope	FortiGate v7.2.5, 7.4.1.
Solution	This behavior matches with the known issue ID 0944465 On FortiOS v7.2.5/7.4.1, if FortiAPs and Fortiswitches connect to a non-management VDOM, the registration via FortiGate will not work. Fix: Currently, the fix is on FortiOS v7.2.6. Monitor the release notes for the fix on the v7.4 branch: FortiGate / FortiOS Workaround: Switch the FortiAPs and FortiSwitches into a management VDOM.
