¿There is communication between Varnish host and 188.8.131.52 machine??
Try first making " telnet 184.108.40.206 80 " in order testing there is no
firewall or a rule configured in webserver.
If comunication is fine, the problem must be in VCL configuration. Try
executing varnishlog while you are testing and look for errors in output.
In Solaris is also important to run Varnish with proper parameter that are
I had a lot of comunication problems without parameter:
* -p connect_timeout=0s # Important bug work around for Solaris*
