Unable to Connect to the remote server

Hi
I’m not very technical so be gentle!
I’m getting the above error message when trying to access mycloud. I’ve done a 4 second reset, checked the internet connections, etc but to no avail. I also upgrades to OS5 and the dashboard has been telling me that its generating previews for hours. I’m ready to throw the entire thing out of the window. Can anyone help?
Thanks
