VCSA7 : No healthy upstream!


 I think many of us saw something like the following error when the deployment operation of VCSA7 has been finished. First of all, I decided to go directly through the VAMI and check the health of services, but everything worked correctly. Truly some of them are healthy with a warning, but after a restart, all of them are healthy, but sadly the problem still exists, even after restart the vCenter server. I searched inside the log files and nothing especially found that is related to this matter. 


You know if you type the IP address of the vCenter server, it will be redirected to the FQDN (if you set it correctly meantime of the deployment phase), So I decided to investigate more inside the "/etc/hosts" then create a backup and change the primary file's content, changing each line of IP/FQDN combination to the IPv4 and IPv6 loopback address form and also replace the "localhost" instead of FQDN, Something like the following picture.


 




 


Finally, after the second restart, the mentioned warning is gone.
