Invalid Key Pair
## Error ``` {"code": 568, "message": "Invalid key pair"} ``` ## Troubleshooting | Reason | Solution | | --- | --- | | The signature validity period is 15 minutes by default — the signature has expired | Regenerate the `timestamp` and `signature`. | | The `timestamp` is supposed to be in milliseconds (ms), but was generated in seconds (s) | Regenerate the signature using a timestamp in **milliseconds**. | | The `timestamp` and `signature` are not generated correctly | Please refer to the [Generative Signature Method](http://docs.paraverse.cc:10086/doc/415/) for the correct implementation. |
