I don't know if this has been done before but being new to Linux Zorin I found this
fix. I was using my Cell in USB tethering and came across this, funnily it does not happen using the Cell in WiFi mode. See screen shots.
I had the same thing happen, but it was on our WiFi connection with a cable modem. The "Automatic Updates" slider was off. I searched and searched for a solution... come to find out, toggling the "Automatic Updates" slider to on, then back to off fixed it.
I am trying to figure out if this is a Help Question or a Tutorial
If the latter, maybe should be moved to "Tutorials" or "Chat about Zorin" forum section?
