squid - 503 鱿鱼服务不可用

Question

我正在尝试在 Google 云引擎上设置鱿鱼，但每个网站都收到503 Service Unavailable。

curl -x http://35.xx.xxx.xxx:62401   -I http://www.squid-cache.org/Support/
HTTP/1.1 503 Service Unavailable
Server: squid
Mime-Version: 1.0

X-Cache-Lookup: MISS from google_proxyv1:62401
Connection: keep-alive

我将我的鱿鱼配置剥离到下面的最小值

acl CONNECT method CONNECT
http_access allow CONNECT 
# And finally allow all  access to this proxy
http_access allow all
# Squid port

squid 正在监听 ipv4，因为我只保留了一个 ipv4 地址

sudo netstat -antp | grep 鱿鱼

tcp        0      0 0.0.0.0:62401           0.0.0.0:*               LISTEN      16811/(squid-1)   

但是访问日志显示它是否仍在尝试连接到 ipv6 地址

1549028715.317      3 35.xx.xxx.xxx TCP_MISS/503 357 HEAD http://www.squid-cache.org/Support/ - HIER_DIRECT/2001:4800:7812:514:be76:4eff:fe04:5ca1

我已经在 Google 云引擎上打开 62401 tcp
