proxying SSL -> SSL

[lejeczek <peljasz@xxxxxxxxxxxxxxxxxxxxxxx>]

    Hi guys.
        
        I've sroogled & have found people suggesting working
        examples, I thought I had some notes but now I'm thinking I read
        that it should not work..
        so I'm not sure what to think of this seemingly setup:
        
        <VirtualHost siem.mine.priv:443>
          ServerAdmin webdev@xxxxxxxxx
          ServerName siem.mine.priv
        
          ErrorLog /var/log/httpd/siem.mine.priv-error_log
          CustomLog /var/log/httpd/siem.mine.priv-access_log common
        
          SSLProxyEngine on
          #SSLEngine on
          #SSLProxyVerify none
          #SSLProxyCheckPeerCN off
          SSLCertificateFile      /etc/pki/tls/certs/siem.mine.priv.crt
          SSLCertificateKeyFile  
        /etc/pki/tls/private/siem.mine.priv.key
          #SSLProxyCACertificateFile
        /etc/wazuh-indexer/certs/root-ca.pem
          #SSLProxyMachineCertificateFile
        /etc/wazuh-indexer/certs/admin.pem
        
          RequestHeader set X-Forwarded-Proto “https”
          RequestHeader set X-Forwarded-Port “443”
        
          ProxyRequests Off
          #ProxyPreserveHost on
          #ProxyPass         /  https://127.0.0.1:8443/
          #ProxyPassReverse  /  https://127.0.0.1:8443/
        
          <Location "/">
            # preserve Host header to avoid cross-origin problems
            ProxyPreserveHost on
            # proxy to 
            ProxyPass         https://127.0.0.1:8443/
            ProxyPassReverse  https://127.0.0.1:8443/
          </Location>
        
        </VirtualHost>
        
        As you can see I've fiddle whit all those options in different
        combinations but nothing works for me.
        Would you know how to fix or... perhaps you have Apache
        rev-proxying to Wazuh?
        
        errors in log:
        ....

        many thanks, L.
