Presence Service - 403 error

I updated Openfire to 3.9.1, and installed the Presence service so as to put status in our Confluence wiki.

Presence installs fine, and I configured the plugin to allow anyone to see status (not just subscribers), but when I visit the URL like:

http://im01:9090/plugins/presence/status?jid=user@domain.tld&type=xml

I get this:

It happens for valid & invalid jid’s, not sure where to go from here. Any idea what I’ve done wrong?

Server => Server Settings => Presence Service => Presence Availability => Anyone did the trick for me.
