官方限流组件在反向代理的情况下有问题

环境

centos7,webman1.6,在本地使用openresty做反向代理.
http://本地域名:8080 反向到 192.168.31.11:8787

<?php

namespace app\middleware;
use Webman\Http\Request;
use Webman\Http\Response;
use Webman\MiddlewareInterface;
use Webman\RateLimiter\Limiter;
class LimiterMiddleware implements MiddlewareInterface {

    public function process(Request $request, callable $handler): Response {
        var_dump($request->getRealIp()); // 固定值,没问题
        Limiter::check($request->getRealIp(), 3, 15, '限流了');
        $response = $handler($request);
        return $response;
    }
}

这段代码再不使用反向代理情况下,非常正常.使用了反向代理后,最少有3分之2的请求拦截不了,也就是说无法触发限流.

这是我的nginx配置
