RAK762 no longer connecting to AWS IoT Core

This week I moved the gateway from our home to our farm to put it into “production” mode, as I already finished a sample proof of concept at home, and when plugging it at the new site, it just won’t connect to AWS IoT Core as it was doing back at home.

At home, it was connected to the internet via ethernet at Wi-Fi, and I did the same to keep things as “constant” as possible. Checked endpoint connectivity using cUrl, and works fine. Back at home, we have fibre-based internet; at the farm, we have a Starlink-based connection.

System logs don’t show any relevant info, warning or errors.

What could be wrong? What should I provide for further investigation?
