The connection to cloud services is registered to the domain name you set in Logpn settings, see Domain (not in SwyxON and SDC).
Once the connection is established, you cannot change the domain name.
If you have not entered a domain name, a random name, such as "5wmoue.swyx.net" will be generated when connecting to cloud services.
