Yeah, I've tried this already.
I've just restarted my computer and run Apex. Then I tried to connect to several internet hubs and it worked, but after a couple of minutes hubs began to disconnect one by one. When I try to reconnect (even after restarting Apex) every (internet) hub says thet it is connected and nothing else happens (there is no users or any messages in the chat except "connecting to hub ....", "connected").
