Why Is the Purchase Button Unavailable When I Create a Cluster?

The possible causes for unavailable purchase button during cluster creation are as follows:

• The flavor to be purchased could be sold out, or the region does not have such a flavor.

  Solution: Before purchasing, check whether the flavor is available in the region, or purchase a package after the cluster is created. After the package, the package is automatically associated with the cluster.

• The account could be in arrears or restricted, so new resources cannot be created.

  Solution: If your balance is insufficient, top up the account to write off the overdue amount.
