Question

我使用Nginx作为反向代理，当我从浏览器（Chrome，Firefox）访问网址时，它将显示504网关超时。但是，当我使用curl或wget访问网址时，它可以正常工作。这真是一个奇怪的问题，任何人都可以给我一些帮助吗？

上游配置为：

upstream default-nginx-z-80 {
    # Load balance algorithm; empty for round robin, which is the default

    least_conn;

    keepalive 32;

    server 10.1.228.195:80 max_fails=0 fail_timeout=0;

}

服务器配置

server {
    server_name z-ingress.mixhub.cn ;

    listen 80;

    listen [::]:80;

    set $proxy_upstream_name "-";

    location / {
