InvalidSignature error

Hello,

Since yesterday, an error is appearing in the Content Egg module when I search for a product on Amazon. The content of this error is the following :
“Error: InvalidSignature: The request has not been correctly signed. If you are using an AWS SDK, requests are signed for you automatically; otherwise, go to https://webservices.amazon.fr/paapi5/documentation/sending-request.html#signing.”

I did a google search and I haven’t found any topic about this problem with the Content Egg plug in.

It seems like the server is having a problem sending the correct signature. But the API keys I entered in Content Egg are the same than when I bought the plug in, and they did not change since. All was working perfectly until yesterday.

Could you please tell me what the problem could be ? And what should I do in order to correct this problem ?

Thanks in advance,
