The ESXi host displays a 'Not Responding' status in vCenter.
Executing '/etc/init.d/hostd status' and '/etc/init.d/rhttpproxy status' confirms that both services are stopped.
Attempts to restart the ESXi hostd service result in the following error within /var/run/log/hostd.log:
<YYYY-MM-DD>T<HH:MM:SS> Cr(###) Hostd[#######]: [Originator@#### sub=Default] error: N7Vmacore23FileIONotFoundExceptionE(Could not find file : /etc/vmware/rhttpproxy/endpoints.conf)
VMware vSphere ESXi 8.0.x
The file /etc/vmware/rhttpproxy/endpoints.conf is missing, which prevents the hostd service from starting.
Restore the /etc/vmware/rhttpproxy/endpoints.conf file by copying the contents from a functional ESXi host of the same version, then restart the rhttpproxy, vpxa and hostd services.
/etc/init.d/rhttpproxy stop
/etc/init.d/rhttpproxy start
/etc/init.d/vpxa stop
/etc/init.d/vpxa start
/etc/init.d/hostd stop
/etc/init.d/hostd start
Or
Restart the affected ESXi host.
