Depending on the upgrade path you followed, that could be the problem. 220.127.116.11 doesn't support a direct upgrade from 3.4.2. However, it is also possible that the device needs to get an update from the internet first for GAM and AV and then subsequent updates should be fine. If there was an unsupported upgrade path, you are going to need to reimage the appliance. Contact support and they can assist with that.
