We got this issue resolved, the problem was within Windows not RCForb Client.
There are several ways to get RCForb to "not see" the internet. First you can open Internet Explorer, and goto "Work Offline" mode. This will make RCForb have trouble seeing the internet / connecting to website. Also if under Internet Options in the Connections tab. If the "proxy settings" or anything else in there isn't setup right. RCForb will have this problem. Screenshots below...
