I upgraded the vCenter and vCO Appliance in 5.1 Update 1 but I have a big probleme with the vCO configuration.
In first time the Appliance lose the DNS server and don't communicate with my vcenter, I tried to reconfigure the vco (remove/add cert, unregistered vcenter,etc.) but now I have a pb with the license (see screenshot vCO error1)
And I have a second error with the vcenter plugin now (see screenshot vCO error2)
If anyone have an idea ?
It seems that you have an issue with the certificate of the appliance. it may need to be regenerated. I know how to force it on the vCenter VA but never did it on the vCO one.
I would advise opening a support request to get the proper procedure.
