Have you ever experienced in HX deployment, installer was stucked at starting. WE're currently adding a node in a cluster and We're using the same installer we used in creating the cluster. new node is the same as the existing nodes.
You can try to reset it by going to https://$InstallerIP/api/reset. Alternatively, SSH to the Installer VM and `restart stDeploy`. /var/log/springpath/springpath_validation.log may also point you in the right direction.
