When navigating and making changes in some settings under Management Center UI > Administration > Settings, clicking "Save" and "Activate" , management center becomes unresponsive.
Management Center
Expected behavior
Below are the following settings that needs to be Activated and restart of Management Center service.
Navigating to advance URL https://mc-ip:8082/api/system/settings should also tell which settings requires a restart.
Recent releases of Management Center versions would have a pop-up Confirmation window Administrator with messaging that a restart is required.
E.g
Note: Restart Management Center manually if Device Communications settings has been changed via CLI/SSH as this will not give prompt that "A restart is required"
