calc ak sk signature fail:signature expired

When an API is called, the "Incorrect IAM authentication information: calc ak sk signature fail:signature expired" error is reported. It indicates that the AK or SK has expired.

Check whether you are using a temporary AK/SK or a permanent AK/SK. For details about how to obtain a temporary key, see Obtaining a Temporary Access Key and Security Token Through a Token. For details about how to obtain a permanent key, see My Credential.

If this error is reported for a permanent AK/SK, check whether the server time is consistent with the network time. After the time is synchronized, the alarm is cleared.
