I want to avoid the :9090 in the browser and, since I have Apache HTTPD
as a dependency of another tool in my stack I though about proxying
the 
ports 80 and 443 to 9090.

I wrote this config based on some reads on internet:

 <VirtualHost *:80 *:443>
     ProxyPreserveHost On
     ProxyRequests Off
     ServerName myserver.com
     ProxyPass / http://localhost:9090/
     ProxyPassReverse / http://localhost:9090/
 </VirtualHost>

When I hit https://myserver.com I see the cockpit's login page, but if
I try to login it just reload the login page as soon as I hit Log In
button.

I fired a journalctl in the server and found a timeout being reported
by cockpit-ws:

Any idea on how to troubleshooting this? I fell like something is missing in my httpd configuration. After login I 
see the login page again as if the proxy was breaking the backend redirect, ...
