Can't add guests

[Sergio 4]

I'm unable to create a new guest. I created the user in connect, but when I send teh invitation on the server users management, the working animation stays turning forever.

Is it something that I could be missing?

 

If I signin with the recently created user in connect, directly shows my server, and when I select it, It shows my users. I don't know why it has this behaviour, as I did nothing to add this information. I whent directly to the register screen at the web. !!!!????

 

I can access the server through https and connect from outside my LAN.

Thanks.
