What's strange about that is that I didn't make any changes at all to the connection code with any of the last few updates. I do know that Windows can update Windows Firewall settings when an app is updated, so I'm not sure if that is related. It may be worth backing up your library under Settings->Backup and Restore->Backup Library, uninstalilng MobileSheets, reinstalling it, and then restoring your library to see if it eliminates this issue. That would also reset the firewall settings in Windows for MobileSheets. Also, as a side note, if you look at the properties of your network in Windows, do you have it set to "private" instead of "public"? That is important for preventing network traffic from being blocked between apps on the same network.
