Varnish 500 Backend Fetch Failed when varnish is started as service

[Debraj Manna]

I have changed /etc/default/varnish. It looks something like below:-

START=yes
NFILES=131072
MEMLOCK=82000
DAEMON_OPTS="-a 0.0.0.0:6081 \
             -T localhost:6082 \
             -f /etc/varnish/prudsys.vcl \
             -S /etc/varnish/secret \
             -s malloc,1G"

My prudsys.vcl looks like below:-

vcl 4.0;
backend default {
    .host = "146.88.25.40";
    .port = "8080";
}

I have also attached my /etc/init.d/varnish script
