Why Does Cluster Creation Fail?

The following reasons may cause cluster creation to fail:

• Insufficient resource quota. You are advised to increase the resource quotas.
• The value of Port Range/ICMP Type in Security Group does not include port 9200. Modify the security group information or select another available security group.
• For cluster version 7.6.2 and later versions, the communication port 9300 is enabled on the subnet of user VPC by default. When you create a cluster, check whether the selected security group allows traffic from communication port 9300 in the subnet. If it does not allow traffic, modify the security group or select another security group.
