Empty Node-RED palette?

I have an Ekrano that I use for testing Node-RED on my desk.

The Node-RED palette is empty (no packages) when I hit Node-RED over local ethernet.

But it shows the usual thousands of packages when I hit it via the VRM.

Either way - direct over LAN or via the VRM, I get this new behaviour in the debug console:

Because this Ekrano had run various betas, I completely blew it away with a full restore with an image of 3.73 (not just the “reset to defaults” procedure). This did not change the results.

I suspect it is not Venus version dependent because a Cerbo with a 3.70 install is doing the same thing (no packages) - but I have another Cerbo with 3.73, which does show packages. Doesn’t seem to be connected with local network security profile etc or the telemetryEnabled thing, but I thought I’d mention it.
