Jitsi / XMMS: всегда в режиме офлайн, не могущий соединиться

Я попробовал Jitsi, (xmpp учетная запись созданная канавка, Jitsi был успешен). Мое пользовательское состояние всегда остается на "офлайновом", даже если я нажимаю "онлайн". Колесо значка вращается неограниченно долго, говоря, что оно ищет что-то. Но ничего не происходит.

Вот консольный возврат:
