Check the following information:

  1. If the system reports that the user name or password is incorrect, enter the correct user name and password.
  2. If the system reports that you could not connect to the management node, run the zstack-ctl status command to check whether the management node service is running properly.
  3. If you still could not connect to the management node, perform login via cli.
    [root@localhost ~]# zstack-cli  #Go to the CLI mode.
admin>>> LogInByAccount accountName=admin password=password #Log in to the CLI. Default user name/password: admin/password.
  4. Check whether the related Java process cannot run due to zombies in the process. If yes, restart the management node service.
