I'm experiencing the same thing. Trying to connect to 2 laptops in Spain but they either do not appear to be available (offline) or appear to be online but when you attempt a connection they go offline again.
Using the standard INternet_ID connection method.
id.remoteutilities.com can be found using a DNS lookup in Chrome.
I can succesfully connect to the remote laptops using Google Chrome Remote Desktop.
I'm a new user and this is not a great start.
