What is the full request sent in each case?

"curl -v" to show what it sends. Or "tcpdump" on the nginx server to
see what it receives.

If you see different headers sent from your code and curl, perhaps try
adding or removing one at a time to see if there is one that matters.

Purely on the lines you have shown: does your code or config do anything
based on $http_user_agent or the equivalent?
