In order to connect to Dropbox or Google Drive, I use a generic web view component which is basically a stripped down version of internet explorer (it's what Microsoft provides). So what you are seeing is that internet explorer type component saying it can't connect to the website for the cloud service you selected. Is there something on your box that would prevent internet explorer from connecting to one of those websites? Have you changed the default settings in internet explorer for security or do you have other things on your system which would be preventing that such as a proxy or vpn?
