Proxy 進自己的localhost被擋?? - Linux

請問一下
(假設我的主機ip是123.123.123.123 domain name 是 abc.tw)

我的主機上面跑 squid
當我使用該 proxy 的時候

連 123.123.123.123 是正常的

但是連 http://abc.tw
卻會出現以下錯誤
-----------------------------------------------
ERROR

The requested URL could not be retrieved

While trying to retrieve the URL: http://abc.tw/

The following error was encountered:

Connection to 127.0.0.1 Failed
The system returned:

(111) Connection refused
The remote host or network may be down. Please try the request again.

Your cache administrator is root.

請問
我是哪邊擋錯了嗎???
