Dear Sir,

I'm trying to run Winflector behind a APACHE reverse proxy using web launcher.

I'm able to access to web application launcher but when I launch the application, I get "Error 52: Cannot connect to Winflector Server".

Apache virtual host configuration is:

<VirtualHost *:3022>

ServerName www.domain.com

#...

 

<Location />

    Require all granted

</Location>

 

<Location /virtual/>

    Require all granted

</Location>

 

ProxyRequests Off

ProxyPreserveHost Off

SSLProxyEngine on

SSLProxyVerify none

SSLProxyCheckPeerCN off

SSLProxyCheckPeerName off

SSLProxyCheckPeerExpire off

 

    ProxyPass / https://www.backend.domain.com:3022/

    ProxyPassReverse / https://www.backend.domain.com:3022/

 

    ProxyPass /virtual/ https://www.backend.domain.com:3022/virtual/

    ProxyPassReverse /virtual/ https://www.backend.domain.com:3022/virtual/

 

    ProxyPassReverseCookieDomain  "backend.domain.com" "domain.com"

 

    SSLEngine on

 

    SSLCompression off

    SSLSessionTickets off

 

    #   Server Certificate:

    SSLCertificateFile "${SRVROOT}/conf/certificate/VSV-GTW-SERVER.crt"

    #   Server Private Key:

    SSLCertificateKeyFile "${SRVROOT}/conf/certificate/VSV-GTW-SERVER.key"

 

#...

</VirtualHost>   

Do you know where this error can come from? Is there something missing in Apache configuration?

Hello,

Web clients use websockets to connect, so your proxy must support websockets to pass traffic from web clients to the application. Websocket is created only when you launch the application, so you have access to the launcher and cannot start the application.
