Error Page Customization
You can configure custom error pages to replace the default error responses for different HTTP status codes, providing users with a more user-friendly experience.
Supported Status Codes

|---|---|
| 400 | Bad Request The server could not understand the syntax of the request. |
| 403 | Forbidden The server understands the request but refuses to authorize it, often due to insufficient permissions. |

| 500 | Internal Server Error A generic error indicating that the server encountered an unexpected condition. |
| 501 | Not Implemented The server does not support the requested functionality. |
| 502 | Bad Gateway The server received an invalid response from the upstream server. |
