Did you enable USB mode under USB Application > 3G/4G?

Yeah I did enable that
Was having another device with older model that Working fine
But while I swap to the latest model which support 4g ,LTE then facing this issue
The model was not on the list

I was having this same error while tethering my Nexus 5. I am getting out to the internet fine, but I am thinking it is related to the WAN IP that is assigned to the router being a private IP, so you are effectively double nat'ed.

On mine, the error did go away and the device connected fine. Maybe your error is staying though, which could be a different issue.
