用nginx做對應多網站
abc.test.com.tw可以正常
cde.test.com.tw卻出現502 Bad Gateway
請問以下設定哪邊會有問題嗎

vip 192.168.100.190
nginx 192.168.100.191
192.168.100.192

nginx.conf
upstream abc_pool{
ip_hash;
server 192.168.100.20:443 weight=4 max_fails=2 fail_timeout=30s;
server 192.168.100.21:443 weight=4 max_fails=2 fail_timeout=30s;
}

upstream cde_pool{
    server 192.168.100.30:443 weight=4 max_fails=2 fail_timeout=30s;
    server 192.168.100.31:443 weight=4 max_fails=2 fail_timeout=30s;
}
include /etc/nginx/conf.d/*.conf;

/conf.d/default.conf
