LiveStream configuration error - Invalid specified URL

I just installed jfcbconnect, login authentication is fina, as well as like buttons and comments.

I'd like to insert a live stream box at the frontpage of pibid.cct.ufcg.edu.br to be used as the format chat module (locally hosted), e.g., as a mean of logged in people to interact lively when needed.

I'm not sure how to configure the module, I positioned at footer and inserted VIA URL as pibid.cct.ufcg.edu.br/portal. At the frontend I get an error saying

Erro de configuração de caixa de transmissão ao vivo
Via inválida de URL especificada. Para informações detalhadas sobre o Live Stream Box, por favor visite Developer Wiki.

(Configuration Error in live stream box
Invalid specified URL. Check developer wiki)

If I access developer wiki my api number appears correctly and anlo a live stream box inside facebook.

What I am getting wrong?

Thanks in advance
