Hello, I'm trying to setup the sieverules plugin for roundcube. When going to settings->filters I get an error 'Unable to connect to sieve server"

My setup is virtual email using dovecot,postfix,mysql,postfixadmin/roundcube

I've confirmed dovecot-managesieve is working:

root@mail /var/log # netstat -anop |grep 4190 tcp 0 0 0.0.0.0:4190 0.0.0.0:* LISTEN 23613/dovecot off (0.00/0/0) root@mail /var/log # nc localhost 4190 "IMPLEMENTATION" "Dovecot Pigeonhole" "SIEVE" "fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave imapflags notify" "NOTIFY" "mailto" "SASL" "PLAIN LOGIN" "STARTTLS" "VERSION" "1.0" OK "Dovecot ready."

Here are the relevant options for plugins/sieverules/config.inc.php:

$config['sieverules_host'] = 'localhost'; $config['sieverules_port'] = 4190; $config['sieverules_auth_type'] = null; $config['sieverules_usetls'] = FALSE;

In my apache2.log:

[Tue Oct 07 11:12:43 2014] [error] [client xx.xx.xx.xx] $addr cannot be empty (): , referer: http://mail.example.org/webmail/?_task=mail [Tue Oct 07 11:12:43 2014] [error] [client xx.xx.xx.xx] Not currently connected (1): , referer: http://mail.example.org/webmail/?_task=mail

Any help would be greatly appreciated.
