名稱或服務未知：AH00547：無法解析主機名

連接到我的個人網站時，我收到SSL_ERROR_RX_RECORD_TOO_LONG來自 Mozilla Firefox 的錯誤消息：

Secure Connection Failed

An error occurred during a connection to www.fturco.net. SSL received a record that exceeded the maximum permissible length. Error code: SSL_ERROR_RX_RECORD_TOO_LONG

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

我的網站託管在 VPS 伺服器上，但我試圖從家裡的個人電腦訪問它。

此錯誤消息僅在我重新啟動 VPS 伺服器後立即發生。啟動後，如果我重新啟動httpd.service問題就消失了。

這些是來自的相關消息/var/log/httpd/error_log：

這是我的/etc/hosts文件：

127.0.0.1 localhost vps

命令hostname返回vps。

我的 VPS 伺服器執行 Arch Linux 和apache-2.4.23-1.

我該如何解決這個問題？

似乎VirtualHost指令是錯誤的。正確的方法是：

<VirtualHost *:443>
 ServerName www.fturco.net
 DocumentRoot "/srv/http/www"
 ErrorLog "/var/log/httpd/www/error_log"
 TransferLog "/var/log/httpd/www/access_log"
 SSLEngine on
</VirtualHost>

唯一的區別在於前兩行。
