Nano Loco M2 not providing master mesh node info

Recently upgraded a Nano Loco M2 to 3.18.9.0.   It will not provide the info to Winlink Express to obtain WL2k post office info.

All the other nodes on the mesh (Bullets, Air Grids, Rockets) running 3.18.9.0 do provide the info.

If I swap out the LocoM2 for an AirGrid (which isn't practical for permanent install) then the issue goes away, so its got to be LocoM2 related. 


Winlink would report:  Error getting master node info.  Unable to get info from master node ve7ahe-ecommtrailer.local.mesh
Your computer must be connected to an AREDN MESH node running firmware version 3.17.1.0RC1 or later.

Here is the JSON file output it makes.
