A 监听 ipv6，想反代不支持 ipv6 的网站 B，结果报错：failed (97: Address family not supported by protocol)

    listen [::]:443 ssl http2;
    listen 443 ssl http2;
    location / {
    proxy_redirect off;
    proxy_bind $server_addr;
    proxy_set_header Host $http_host;  
    proxy_set_header X-Real-IP $remote_addr;  
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Scheme $scheme;
    proxy_pass http://127.0.0.1:9093;
    }

请教如何实现呢？

找到原因了，删掉这个就好了：proxy_bind $server_addr;
