There is no "limit_req" directive anywhere in your config, so it's 
not a surprise rate limiting does not work.

You have to configure both "limit_req_zone" (to configure shared 
memory zone to store states) and "limit_req" (to configure 
particular limits in particular locations), see 
details here:
