在ec2上安装varnish之后无法访问phpmyadmin

I have installed varnish. For this, I have changed the apache port from 80 to 8080 and in my varnish file config default.vcl I have this:

backend default {
.host = "127.0.0.1";
.port = "8080";
}


 ## Multiple virtual hosta
sub vcl_recv {
if (req.url ~ "^/phpmyadmin") {
return(pass);
}


if (req.http.host ~ "mydomain.xxx(:[0-9]+)?$") {
 set req.backend = default;
 }



}
sub vcl_fetch {
if (req.url ~ "^/phpmyadmin") {
return (hit_for_pass);
}

}

but when I want to access phpmyadmin on http://xxx.xxx.xxx.xxx:8080/phpmyadmin, I get no access.

Any idea about this problem?

If you want to access port 8080 externally you need to allow it on the security group that instance is using.

For example:
