'Your host license expires in 0 days. The host will disconnect from vCenter Server when its license expires'
Auto Deploy sets a one day evaluation period for all stateless hosts which are rebooted after their evaluation period of 60 days had expired. This triggers a alert in the vCenter which is captured by the monitoring software.
Broadcom Engineering is aware of this issue. This issue will be fixed in a future patch release for vCenter 8.x and ESXi 8.x.
