Unable to access Webgui/SSH for one of the ESXi Host.

Hi Gurus,

I have a 2 node ESXi Host Cluster managed by vcenter. I am running ESXi 6.5 U2. Both the ESXi is managed by vcenter and both the ESXi is showing as green in the vcenter console. Both the ESXi host has a similar configuration. When I try to access one of the ESXi hosts using WebGUI/SSH it is not accessible, however, the host is pingable. The Lockdown is disabled on both the host.

     I also tried to restart the SSH, ESXi SHell, DCUI Daemon from the Vcenter console on the ESXi host having the issue but still, the issue is not resolved.

Any suggestion or guidance by the Gurus is highly appreciated.

Thanks

AJ
