I can't find any reference of a similar error on the Internet. My best guess is that you've either modified your proxy settings or that your firewall is blocking the connection. If you've checked and neither of these solutions are working for you, I recommend manually adding one or two cameras to see if you can get Eye Cloud to work like that.
Lastly, you can try contacting the company that develops the application using the following email address: email@vstarcam.com .
