我無法讓 https://sendsonar.com 正常工作，但 sendsonar.com 和 https://www.sendsonar.com 工作正常

我正在嘗試讓我們的域 - https://sendsonar.com - 轉到https://www.sendsonar.com，但由於某種原因，這失敗了。這是捲曲輸出：

yo@ubuntu-i386:~/Sonar$ curl -kvI https://sendsonar.com
* Rebuilt URL to: https://sendsonar.com/
* Hostname was NOT found in DNS cache
*   Trying 50.63.202.28...
* Connected to sendsonar.com (50.63.202.28) port 443 (#0)
* successfully set certificate verify locations:
*   CAfile: none
 CApath: /etc/ssl/certs
* SSLv3, TLS handshake, Client hello (1):
* Unknown SSL protocol error in connection to sendsonar.com:443 
* Closing connection 0
curl: (35) Unknown SSL protocol error in connection to sendsonar.com:443 

如果我去 https://www.sendsonar.com，這是 curl 輸出

yo@ubuntu-i386:~/Sonar$ curl -kvI https://www.sendsonar.com

...and so on

我們的域名和 ssl 證書是從 Godaddy 購買的，伺服器在 Heroku 上。

我不確定它是在 Godaddy 還是 Heroku 中的設置，並且我已經盡我所能探勘了我有限的知識。

謝謝你的幫助。

您似乎正在使用 GoDaddy 將https://sendsonar.com/重定向到 Heroku 託管的www子域。GoDaddy 的 DNS 管理器的重定向不支持 HTTPS（因為 GoDaddy 的重定向服務伺服器沒有安裝您的 SSL 證書）。
