我在新的專用服務器上安裝了docker（在通用的ubuntu 14.0 - linux kernel 3.13.0-71上）。 我安裝了一個ubuntu docker鏡像來測試環境。 （docker run -it ubuntu bash），我用openssl支持安裝了curl。無法從Docker鏡像連接到HTTPS（443）
當我嘗試獲取HTTP頁面的內容時，我沒有任何問題。當我嘗試加載HTTPS頁面，我的連接被拒絕：
[email protected]:/# curl https://www.google.com
curl: (7) Failed to connect to www.google.com port 443: Connection refused
我：
[email protected]:/# curl -V https://www.google.com
curl 7.35.0 (x86_64-pc-linux-gnu) libcurl/7.35.0 OpenSSL/1.0.1f zlib/1.2.8 libidn/1.28 librtmp/2.3

，如果我嘗試登錄跟蹤文件中的，我有：

我什麼我可以做:( 這不是一個DNS問題，因爲我可以ping端口80上的服務器或捲曲的HTTP內容只涉及到SSL連接有點失落。 有S^omeone在這裏有關於這個問題的任何想法？
謝謝
您能建立從主機系統到Google（或任何地方）的SSL連接嗎？這可能是防火牆問題？ – helmbert
是的，如果我使用主機系統的命令curl https://www.google.com，我會收到一個有效的html內容 – user1649194
