What does your nginx error log say?

Do you know which add_header lines are breaking the configuration? If not, comment them all out then enable them 1 by 1, reloading nginx to see which one(s) is/are the problem. I would begin by commenting out the block:

add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Credentials' 'true';
add_header 'Access-Control-Allow-Headers' 'Authorization,Content-Type,Accept,Origin,User-Agent,DNT,Cache-Control,X-Mx-ReqToken';
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS, PUT, DELETE';
add_header PS 1

The problem could be that you're setting headers not supported by the core httpHeaders module. Installing the NginxHttpHeadersMoreModule may be helpful.

Also, try replacing the two add_header lines int the location ~* \... with the following:

add_header Pragma '';
add_header Cache-Control 'public, max-age=31536000'

Is there a reason you have the gzip configuration here and not in your global nginx.conf?
