Clean cache not purge cache

[arisdario]

I have an issue trying to purge the cache front backend but on clean the cache, all caches it doesn't clean.

in the varnish_log i have this error:

2014-05-28T13:46:13+00:00 DEBUG (7): Purging on server localhost failed (Return status 405). 2014-05-28T13:46:13+00:00 DEBUG (7): Purged Varnish items with parameters array ( 'X-Purge-Host' => '^(www.mydomain.com)$', 'X-Purge-Regex' => '.*', 'X-Purge-Content-Type' => 'text/html', )

I think if 405 status give the purge cache will not work, is there a way to fix it?

Check your VCL and ensure the web server IP is mentioned in the ACL list. Otherwise Varnish won't allow the purge request from Magento.

[arisdario]

I have configured the default.vcl as specified in your module and i have in my default.vcl

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

#### admin backend with longer timeout values. Set this to the same IP & port as your default server.
backend admin {
  .host = "127.0.0.1";
  .port = "8080";
  .first_byte_timeout = 18000s;
  .between_bytes_timeout = 18000s;
}

#### add your Magento server IP to allow purges from the backend
acl purge {
  "localhost";
  "127.0.0.1";
}

Is your web server on the same machine as your Varnish server? If you configure

acl purge { "localhost"; "127.0.0.1"; }

the Varnish server in the PageCache module configuration should be 127.0.0.1. Also make sure the port of the Varnish server is correctly configured (if it is on the same machine Varnish is probably in port 80).

[arisdario]

Yes, the Varnish service is installed in the same server, and yes the port is set to 80 and on Nginx listen port is set to 8080, so in this case varnish is on front.

And yes, you're right, i have set in admin 127.0.0.1 and por 8080 instead of 80 .

Thank you very much for give us the possibility to get Magento Fly !
