I have seen behavior that backs up Ashley's experience, tho I am able to remote in. In my case, I'm using the public server, and see that every few minutes (seconds in some cases) where a host will flicker offline and online again. Noticed this due to having notifications enabled. Using Internet-ID connections, host is a VM on my machine. No changes to the connection's settings besides adding the connection/host to my address book via internet-id and setting the password.
