SignatureDoesNotMatch error

[miatidis-storfund]

Hi,

Lately we often get SignatureDoesNotMatch errors when making Finances API calls:

{"Type":"AmazonMwsAPIError","Code":"GenericError","Message":"The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.","StatusCode":403,"OriginalError":{"Type":"Sender","Code":"SignatureDoesNotMatch","Message":"The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details."}

I wonder if it is a glitch of the Amazon API or e.g. under some conditions the signature that the library generates gets corrupted
