Can't see multiplus in VRM or cerbo

[fernanci]

My installation is 2 years old and I have 2 multiplus in parallel. Since 1 month ago half of the time or more I can’t see inverters in VRM or cerbo, the look “off”, this happen randomly but more or less half of the time everyday.

Try replacing the UTP cable between the inverters and the Cerbo.

I tried it, same results. I checked all cables before trying.For example, today some hours didn’t work, from 12 till 18, and now works perfectly

Finally since 1 month ago there is no multiplus anymore in the cerbo. Tried new rj45 cables with same result.

I reinstalled firmware in the cerbo and upgrade multiplus to 5.60 version

I can see them with victron connect and mk3 cable, but not in VRM.

Could be cerbo failure?
