I am using the newest version of X-ray (3.10.0) to connect to a vCenter (6.5U1d) to have some performance tests for my cluster. At the step 4 (Validation) of creating the target cluster, it failed to validate the cluster.
Error: Target cannot be verified.
After looking into the log, in the HTTP Response body, it contains the 500 Internal Server Error. Still cannot get what it means as everything seems fine and the connection from X-ray VM to cluster still has no problem at all.
