An administrator is able to manage an ESXi 6.x host connected to vCenter Server using the vSphere Web Client but is unable to connect to the host directly. Which action should the administrator take…

Restarting management agents addresses issues where the host is unreachable from vCenter as well, but if management via vCenter is working correctly, the symptom specifically matches Lockdown Mode rather than a failed agent.

Lockdown Mode, when enabled, restricts direct connections to the ESXi host and forces all management traffic through vCenter Server. Disabling Lockdown Mode via vCenter Server restores the ability to connect directly to the host using the vSphere Client or other direct methods.

Disabling the ESXi firewall entirely is an extreme and insecure action that is not the appropriate fix for a Lockdown Mode-related access restriction.

Rebooting the ESXi host would not resolve a Lockdown Mode restriction, as Lockdown Mode persists across reboots and is a configuration setting, not a transient state.
