一个Https问题请教

使用Charles代理抓包，访问某一Https链接失败， 提示网络错误。Charles中看到了如下的信息

URL	https://bar.foo.com
Status	Failed
Failure	No request was made. Possibly the SSL certificate was rejected.
Notes	You may need to configure your browser or application to trust the Charles Root Certificate. See SSL Proxying in the Help menu.
Response Code	-
Protocol	HTTP/1.1
SSL	TLSv1.2 (TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384)
Method	CONNECT
Kept Alive	No
Content-Type	-

不知道为什么Method是CONNECT。

但同时访问同一域名下的另一个Https链接是正常的

URL	https://bar.foo.com/foobar/search?XXX
Status	Complete
Response Code	200 OK
Protocol	HTTP/1.1
SSL	TLSv1.2 (TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384)
Method	GET
Kept Alive	No
Content-Type	application/json;charset=UTF-8

奇怪 为什么同一域名下的Https有的可以成功访问，有的不行。

最后重新装了Charles证书，就都可以了。

虽然解决了问题 但原因仍不明白。
