I am getting an error while testing PayPal Express, the error is:
10002 security header is not valid.
The site runs on an AWS EC2 with nginx and Varnish in front. I use Turpentine for the config and hole-punching. Would this architecture have something to do with it?
I'm not testing on Sandbox mode however the live API credentials are all correct, I've reset it multiple times. I've looked through the logs but I can't find anything significant.

Perhaps the following might be relevant? The token is empty:
