T3 error

I have a Hub 3 in modem mode. On the 26 December it lost connection. On 25/12/2025 00:05:3 I got a "No Ranging Response received - T3 time-out" error. 

This continued until 28 December when I reset the Hub.

This was very inconvenient as I was not at home at the time.
From The logs:

From the above I am still receiving the T3 error. Will this happen again?
How do I stop this from happening again? Also, I would be interested in what caused the error.

    Not seen that problem before but could be any number of reasons

    Are you back in modem mode and is fine?

    your router might of got a bad WAN IP from VM DHCP server (which can happen in router mode) and VM updated the DHCP server wrong and so your router stayed of that bad IP which when you changed to router mode  changed IP again. 

    or maybe the 10. backend Docsis server was updated wrong causing your WAN to be blocked
