Directives proxy_store and proxy_cache can't be used at the same 
time, while in your config proxy_store is inherited from server 
level - so effectively you have both of them switched on in the 
location.

It's the bug that nginx doesn't reject such configuration as 
invalid.

Adding "proxy_store off;" to your location with proxy_cache (or 
just removing it from server block) will resolve your problem.
