Nginx GET Atack

как я могу заблокировать этот метод запроса, потому что я использую все свои ограничения на VPS, и сайт становится недоступным. Я установил его, но это не считается в nginx.conf

 map $request_method $limit { default ""; POST $binary_remote_addr; }  limit_req_zone $binary_remote_addr zone=perip:10m rate=1r/s; limit_req_zone $server_name zone=perserver:10m rate=10r/s; 

и в common_http.conf

if ($request_method !~ ^(GET|HEAD|POST)$ ) { return 405; } try_files $uri $uri/ @backend; 

запрос от nginx access.log
