    • Page is not accessible to users.

    • Page does not exist.

  • Runtime initialization error.

    • JavaScript errors during page load.

    • Missing dependencies or component packs.

    • Cross -Origin Resource Sharing errors.

    • Network-related failures.

  • Environment or org issues.

    • Content Security Policy that blocks resources.

    • Incorrect Lightning component configuration.

    • Verify the user has permission to access the page.
