trying to integrate our S3 server into the cart. I've followed everything to the letter according to the documentation yet this error is persistant:
<Message>Request has expired</Message>
I've read here that Cart66 gives the server a minute of time for someone to download their file. But it looks like it always expires a minute or two before the server time.
It's baffling and I really hope a simple solution I'm just not seeing.
Thanks in advance for any help.
