How to fix this error?

The request received by the system (i.e. a consumer request or provider
response) was protected by an XML Signature to ensure the integrity of
the message.
The system stores the signature values of the XML Signature to prevent
replay attacks within a short timeframe, and checks if such a signature
has been sent before.
The received message contained a signature value it had received before,
indicating a message replay.
