We are using VmWare Vsphere Version 6.5.0 (Build 4887370). Every Sunday our host server is mysteriously shutting down. We get a message from our USV that the host is shut down, however it is the only message we get, so we have looked into the preferences of the USV and of the Vcenter. As usual we have not found anything. Do you have any idea or could you help us? If you need more information feel free to ask.
