Hello TerryD,
Thank you for the new logs. Yes, I can see that the Shake is showing a local network IP address too (a 192.168.x.x) in the eth0 parameter. This confirms that it is connected to the internet and that it can also see a time synchronisation NTP server that it can use.
I can see that, indeed, the Shake was transmitting to our servers until very recently. Do you know if, in the last days/weeks, something has changed in the local network where the Shake is connected? Maybe there is the need to add some exception (or its IP/MAC addresses) to the local firewall, since something similar has been solved in this way in the past.
The procedure to add other DNS, if you want to test it, is the following:
please open the dhcpcd.conf file with
sudo nano /etc/dhcpcd.conf
Delete all the lines that start with static, if present, thus leaving only interface eth0. If the line interface eth0 is not present, then add it. Do not modify anything else.
Then do:
sudo service dhcpcd restart
to make sure those changes took hold and then check the output file with
nano /etc/resolv.conf
This should renew the configuration, and possibly, solve the issue.
