My wordpress site gives error 521 all the times.
When I found this error from my server
$sudo service varnish reload * Reloading HTTP accelerator varnishd Connection failed (localhost:6082) Error: vcl.load 8d6fb6be-9a0a-4896-be47-e2678e3c2617 /etc/varnish/default.vcl failed
I am following this tutorial to set the server up. And, I changed
DAEMON_OPTS="-a :80 \ -T localhost:6082 \ -f /etc/varnish/default.vcl \ -u www-data -g www-data \ -S /etc/varnish/secret \ -s malloc,256m"
/etc/varnish/default.vcl file is copied from the tutorial. All &a mp; has been corrected to &.
It is a fresh droplet. No firewall.
Any clue to resolve it?
