server - nginx rate limiting not working with upstream, directive completely ignored

Question

Nginx is working as a load balancer but not applying rate limiting. It does not matter what rate I set it to in the 'limit_req_zone' directive, it is completely ignored. I want requests from /api/notification/getnotifications (as shown below) to be rate limited for the same ip.

I have a simple server configuration that sends traffic to two servers through upstream.

What could I be doing wrong?

This is my configuration file.

limit_req_zone $binary_remote_addr zone=zonenot:15m rate=1r/m;


log_format upstreamlog '$server_name to: $upstream_addr [$request] '
    'upstream_response_time $upstream_response_time '
    'msec $msec request_time $request_time'
    '$status $body_bytes_sent "$http_referer"'
    '"$http_user_agent" "$http_x_forwarded_for"';
    

upstream lbfrontend {
    least_conn;
    # frontendservers

    server xxx.xxx.xxx:4000;
    server kkk.kkk.kkk:4000;

    
}

upstream lbbackend {
    least_conn;

    # backendservers
    server xxx.xxx.xxx:2000;
    server kkk.kkk.kkk:2000;

}

    
    
    server {

        listen 80;
        server_name xxx.xxx.xxx;

        access_log /var/log/nginx/access.log upstreamlog;

        location / {
            proxy_pass http://lbfrontend;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "Upgrade";
            proxy_set_header Host $host;
        }

        location /api/notification/getnotifications {

            limit_req zone=zonenot;

            proxy_pass http://lbbackend;

            

        }
        location ^~ /api/ {

            proxy_pass http://lbbackend;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "Upgrade";
            proxy_set_header Host $host;
            
        }



        
    }
