Hi,

Before proceeding to "Select Datacenter" tab, on the first tab "Add Account" click "Test Account" green button at the bottom of the form, to make sure that a service account is successfully validated.

Hi Alexey,

Thanks for reply,  I have successfully validate the test account. PFA Screenshot

In the error its showing Discovery status is FAILURE, Identification sections in pattern failed: section: AWS Datacenter identification, error: Match step predicate is not matched.

Well, try a different approach:

Navigate to the Cloud Admin Portal > Manage > Service Accounts;

Choose your Cloud Service Account and click Discover Datacenters related link (If the Cloud Service Account isn't there create one and discover datacenters);

Then click Create Discovery Schedule related link, this should populate some of the fields.

In the Select Datacenters uncheck Discover all datacenters listed below and leave just one under selected column to see if you have the same error

Its showing same error PFB screenshot
