使用Apache反向代理的Softether VPN

Question

我有一个运行redmine和Softether VPN的(azure)服务器。Apache httpd将请求分发给redmine和Softether。

Redmine正在工作，没有任何问题，但我无法使用VPN服务器。从Sothether客户端到服务器的连接可以正常工作，但我没有从DHCP获得有效的IP地址。在apache日志中，我收到以下警告：

AH03408: HTTPS: reusable backend connection is not empty: forcibly closed

在Softether日志中，我得到以下错误：

On the TCP Listener (Port 443), a Client (IP address ..., Host name "...", Port number 7736) has connected.
For the client (IP address: ..., host name: "...", port number: 7736), connection "CID-32-58873B8941" has been created.
SSL communication for connection "CID-32-58873B8941" has been started. The encryption algorithm name is "TLS_AES_256_GCM_SHA384".
Connection "CID-32-58873B8941" has been terminated.

Apache httpd-ssl.conf：

<VirtualHost *:443>
    ServerName ...
    
    SSLEngine On
    SSLProxyEngine On
    ProxyRequests Off
    ProxyPreserveHost Off
    
    ProxyPass / https://localhost/ timeout=3600
    ProxyPassReverse / https://localhost/
    
    SSLCertificateFile "${SRVROOT}/conf/cert.pem"
    SSLCertificateKeyFile "${SRVROOT}/conf/privkey.pem"
    SSLCertificateChainFile "${SRVROOT}/conf/fullchain.pem"
    
    ErrorLog "${SRVROOT}/logs/vpn-error.log"
    TransferLog "${SRVROOT}/logs/vpn-access.log"
    
    <FilesMatch "\.(cgi|shtml|phtml|php)$">
        SSLOptions +StdEnvVars
    </FilesMatch>
    <Directory "${SRVROOT}/cgi-bin">
        SSLOptions +StdEnvVars
    </Directory>
    
</VirtualHost> 

我到底做错了什么？

当服务器位于某些本地反向代理之后时，UDP加速会出现问题。尝试在客户端禁用UDP加速。
