Communication issues between components

Hello everyone, I have a question regarding the Victron Connect/VRM Portal and the communication between all the victron components in my system.
The background: the system is a 3.5kW mobile, solar microgrid designed to provide power to people in need during grid outages.
It consists of all the components as seen in the attached sketches mounted inside a large rolling toolbox.

When i first turned it on after the build process, the Cerbo’s screen, the Portal, and the Smart BMV 712 all showed the same metrics. This lasted for only a day or so. Now only the BMV 712 shows SOC - the portal and cerbo show only a blank space where the SOC and incoming charge numbers should be located. The BMV does not show up on the device list so im pretty sure this is the problem. I have checked all settings, connections, rebooted, yet the problem persists.

If anyone could offer any insight i would be most appreciative.

If the BMV is not in the device list that means that there is communication problem between the GX device and the BMV.

Check/change the VE.direct wire, use another VE.direct port at the GX device.

Worst case the VE.direct of the BMV is somehow broken, in that case you should contact the seller from whom you bought it.
