How Can I Handle Abnormal Status Codes?
Common abnormal status codes include 400, 403, 502, 504, and more. If any of these codes is returned, it is recommended that you access the backend server to check if it can respond properly.
If the backend server responds properly, rectify the fault by referring to Table 1. If the fault persists, contact the customer service.

The request URL or query string parameter sent by the client was too long. |

Internal Server Error |

501 |
Not Implemented |
The load balancer failed to identify the request. The value of the Transfer-Encoding header field is not chunked or identity. |
502 |
Bad Gateway |
|
503 |
Service Unavailable |
The application or backend server was unavailable. Generally, this status code is returned by the backend server. |
