Virtualmin + Varnish Cache and phpMyAdmin

I have install Varnish Cache ver.4 on Virtulmin machine. Varnish config default. There is no problem accessing websites from Virtualmin but cannot get to /phpmyadmin for each virtual host.

Have added

if (req.url ~ "^/phpmyadmin") {
return (pass);
}

to sub vcl_recv without any luck.

Any clue what is gong on?

Thanks
