Stack update not working

Issue

• After the reboot the VM status changed to destroyed.
• Now the application team is trying to bring up the VM using stack update but they are not able to perform stack update.
• We tried to create a new instance using openstack server create and its working fine.

• The application team is using the following command to update the stack

  heat stack-update -f <stack_yaml_file> -e <stack_params_file> -r <stack_name> -P 'pls=N+1
