### HTTP Response Code
| **Response Code** | **Description** |
|-------------------|----------------|
| 200 | Success. (Also used for C interface errors.) |
| 400 | Parameter error |
| 401 | Authentication failure |
| 404 | Interface not found |
| 500 | Internal error |
| 503 | Insufficient system resources |
Starting from `TDengine 3.0.3.0`, `taosAdapter` provides a configuration parameter `httpCodeServerError` to set whether to return a non-200 http status code when the C interface returns an error
| **Description** | **httpCodeServerError false** | **httpCodeServerError true** |
|--------------------|---------------------------- ------|---------------------------------------|
| taos_errno() returns 0 | 200 | 200 |
| taos_errno() returns non-0 | 200 (except authentication error) | 500 (except authentication error and 400/502 error) |
| Parameter error | 400 (only handle HTTP request URL parameter error) | 400 (handle HTTP request URL parameter error and taosd return error) |
| Authentication error | 401 | 401 |
| Interface does not exist | 404 | 404 |
| Cluster unavailable error | 502 | 502 |
| Insufficient system resources | 503 | 503 |

## Configure http return code
taosAdapter uses the parameter `httpCodeServerError` to set whether to return a non-200 http status code http status code other than when the C interface returns an error. When set to true, different http status codes will be returned according to the error code returned by C. For details, see [RESTful API](https://docs.tdengine.com/reference/rest-api/) HTTP Response Code chapter.
## Troubleshooting
You can check the taosAdapter running status with the `systemctl status taosadapter` command.

- `http://<fqdn>:6041/prometheus/v1/remote_read/:db`
## 配置 http 返回码
taosAdapter 通过参数 `httpCodeServerError` 来设置当 C 接口返回错误时是否返回非 200 的 http 状态码。当设置为 true 时将根据 C 返回的错误码返回不同 http 状态码。具体见 [HTTP 响应码](../../connector/rest-api/#http-响应码)。
## 故障解决
您可以通过命令 `systemctl status taosadapter` 来检查 taosAdapter 运行状态。
