Can't create new xmpp account from Jitsi

Hello everyone,

I have openfire installed version 3.9.3 with embedded database.

I create user directly in openfire, it works but I want to create a new xmpp account from Jitsi (view attached file) and I have this error:

Unknown XMPP error (XMPPError connecting to myxmppservername:5222.). Verify that the server name is correct.

One more question: If we can create accounts locally, Is there any way to create automated accounts?

Thanks for help
