An excellent writeup on an issue I’ve seen and reported before. It’s good to see how far Golioth is digging into these very complex issues. So is the medium-term solution to continue setting the secondary DNS manually?

@john.stuewe yes, we would recommend setting the secondary DNS server address manually for the time being. We’ll keep this thread updated as a more robust solution is developed.
Great article - have the same issue with modem_cellular and simcom7080G
