Error with WZone

I’m trying to link my Amazon Associate account using WZone plugin.
I get the following error when I enter the PA API keys.

** Country: United States

Amazon Error: ErrCode = 1 | ErrMsg = [[ Amazon API v5:
http status code = 429
http msg = [429] Client error: POST resulted in a 429 Too Many Requests response: {"__type":“”,“Errors”:[{“Code”:“TooManyRequests”,“Message”:"The request was de (truncated…)
http x-amzn-RequestId = 95a889c2-fefd-44ec-bf9e-67872c468170
errcode = TooManyRequests
errmsg = The request was denied due to request throttling. Please verify the number of requests made per second to the Amazon Product Advertising API. ]]
WooCommerce Amazon Affiliates was not able to connect to Amazon with the specified AWS Key Pair and Associate ID. Please triple-check your AWS Keys and Associate ID.

Is there any solution for this.
