Internal Server Error：


Log page load failure:

Fixed 'enable_restapi' field access error by using proper dictionary key instead of .get() method on cli_parse result object.


Clear Configuration:

Handled expected 500 errors during configuration clear operations (primary/secondary/all) caused by system restart, displaying user notification and redirecting to login page.


3.Backup of VA Instance:

The root cause of the timeout was the CLI waiting for user input. The system attempted to use a duplicate backup name, which triggered an overwrite confirmation prompt. Since the 'YES' command was not provided automatically, the process hung and eventually timed out.
