Cant connect to friend safari any idea's

So I go to my friend safari and enter the door I can connect and log in just fine but when I choose to visit a friend safari after putting the name in and pressing enter I end up with just the rainbow coloured background, no error message, no text box, nothing but the background. If I press x it leaves back to my own safari and if I wait a while it comes up you have been disconnected.

I managed once last night to connect to Lesss’s base but nothing since. Is this a fixable issue? is it because servers are full? or something else.
