ReadyNAS 102 - ReadyCloud Cannot Discover Device

I think that there is a language issue, ie the meaning of "Registering". It may mean either:
a) I Register the NAS to the CLOUD services, so the CLOUD portal knows that my NAS exists. This is done once and that's it.
or
b) the NAS registering to the portal, i.e. saying "Hello, I have been switched on , You know me (because (a) was done in the past) and I am ready to work, I am accessible to my users". This would happen many times, when the NAS's CLOUD services are required.
I think that we did (a); the CLOUD switch is in the ON position, the internet icon is green (so NAS can communicate if so required) but the Services icon is RED. This means that, for some reasons, the NAS is offline, and although it is known to the CLOUD portal, it is actually NOT talking to it right now.
Hence the "Discover" issue, at this moment, is immaterial. The CLOUD portal cannot discover it because NAS is NOT connected to the portal.

Incidentally, we live in a world of immediate access (and maybe getting too spoiled by that), but I wonder if the CLOUD (and ReadyNAS) services work at a different pace, meaning that it is perfectly normal to connect with ReadyNAS, find that my NAS is Offline, but that NAS will come Online 10 minutes later (maybe because my request to connects has "activated" it). Could it be that I been too "hasty" while setting up this 104, and I did not give the CLOUD server enough time to respond?
btw, this was done on a TALKTALK UK account, not blazing fast, but still a theoretical 8Mb/s connection (probably 4Mb/s in real life)

Thanks for being patient with me .....
