@J_S, would you mind submitting a ticket here with your B20X S/N, Remote Assistance = ON, a sketch of connectivity diagram to allow us to take a closer look at the router?
So far, we have seen MAX Transit (Transit, Transit Duo, Transit Pro E) and Balance One (B1, B1 Core) with this symptom. Not too sure B20X would experience the same with the Starlink Gen 2 + Ethernet Adapter (in Bypass mode) setup. Do share the ticket number once you have it submitted.
