Apache 代理返回 403 禁止

Question

我正在尝试设置一个主页，在那里我可以使用代理将我的请求重定向到其他服务器，这样我就有了一个入口点。我曾经让这个设置在运行 WAMP 的 Windows 机器上正常工作。我在 CentOS7 上切换到 Apache，因为我遇到了这个问题。这是我的登陆页面：

<VirtualHost *:443>
    ServerName myhost.duckdns.org
    DocumentRoot /var/www/html/panel

    SSLEngine on
    SSLCertificateKeyFile /etc/letsencrypt/live/myhost.duckdns.org/privkey.pem
    SSLCertificateFile /etc/letsencrypt/live/myhost.duckdns.org/cert.pem
    SSLCertificateChainFile /etc/letsencrypt/live/myhost.duckdns.org/chain.pem
    SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown


    <Directory /var/www/html/panel>
    Order deny,allow
    Deny from all
    Allow from myips
    AuthType Basic
    AuthName "Authorised Users Only"
    AuthUserFile .htpasswd
    Satisfy Any
    Require valid-user
    </Directory>

这是代理通行证

<VirtualHost *:443>
ServerName sickbeard.my.to

    SSLEngine on
    SSLCertificateKeyFile /etc/letsencrypt/live/sickbeard.my.to/privkey.pem
    SSLCertificateFile /etc/letsencrypt/live/sickbeard.my.to/cert.pem
    SSLCertificateChainFile /etc/letsencrypt/live/sickbeard.my.to/chain.pem
    SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown

    <Proxy *>
    Order deny,allow
    Deny from all
    Allow from myips
    AuthType Basic
    AuthName "Authorised Users Only"
    AuthUserFile .htpasswd
    Satisfy Any
    Require valid-user
    </Proxy>
    ProxyPass / http://192.168.0.170:8081/
    ProxyPassReverse / http://192.168.0.170:8081/
</VirtualHost>

我可以毫无问题地访问主页，我可以使用 IP 或主机名访问sickbeard，但使用主机名会给我 403。
