ESXi Host UI is not accessible from UI however CLI and console . The hostd service status shows as running.
ESXi host 7.0.x
ESXi host 8.0.x
The service was restarted while the esxi had an underlying issue, like showing as not responding on the vCenter server.
In logs we see the host-probe.log as hostd service being unavailable.

Hostd service is not updating since the time the host went to hung state.
Due to service being in hung state the ESXi utility would not work.
We reboot the host to resolve this issue, as the service restart made the service to o in hung state.
