After I create a service mesh (that is, create a Dedicated service mesh) for a CCE cluster, it remains in the installing state for a long time and a message is displayed indicating that the user security group rules are successfully enabled.
Log in to the CCE console and click the cluster name to go to the cluster console. In the navigation pane, choose Namespaces. Then, check whether the istio-system namespace exists.
Residual istio-system namespaces exist.
Delete the residual istio-system namespaces and install the service mesh again.
