Hi

This is usually a password issue. Did you change any password?

Hi Diego,

Thanks for your reply, No I didn't change any password for host or vcenter side.

1) Check the DNS entry for host

2) Disconnect and reconnect the Host from vCenter Server

3) Try restarting Management Network from DCUI (requires Downtime if you are on production environment)

If the above steps do not work, please provide me with the Hostd.log from host and vpxa.log from vCenter Server

What version of ESXi?
