Apache + Varnish not work

Hi all
Thanks for your work to create and maintain CentOS Panel, but still need to be improve.

When i tried to use Apache + Varnish (i select this from menu) and after i rebuild vhost i cannot acces the following links:
- Roundcube webmail
- PhpMyAdmin
- Free DNS Manager
- WEBftp

Every time when i tried to access those links i received the error 503 from varnish. If used only apache (with no varnish) everything it's working.

Please advice how to solve this.

Best regards
Alex
