VRM showing the error - Communication monitoring

Since 2 days I get the following message.

I can not access the vrm page.

Everthing is stuck.

When I reboot the cerbo gx everything is working again for app. 20 min, then comes same message again.

What can I do? I tried different firmware and the the setting reboot when no answer after 10 min. Nothing helped.

Do I have to make a reset? But there is no backup funktion. How do I get all settings back? (Internet and network is working fine) regards

Hi @skykay

Are you connecting your GX device to the internet with an ethernet cable?

If you are using a wifi connection, I would suggest trying to connect with ethernet instead and seeing if that resolves the issue.

I used it over cable with no issue for several years. Now with the connection problem I tried wifi, but no change and after each reboot with wifi selected all wifi setting are gone including the wifi connection.

Is it possible to try replacing the Ethernet cable?

Even with a temporary run to see if that helps the situation?

I replaced the cable. No change. The cable does not explain the connection issues with wifi.

Connection issues with wifi are not that unusual, especially with the built in antennas.


Connection issues with Ethernet are unusual, that should be rock solid and stay connected for years without interruption.

Are you running any kind of firewall or other local network routing?

We recently had a case where someone was blocking “Einstein” which is how the Cerbo GX identifies itself without realising it;

I deleted the system from vrm then I made a complete reset. Now it is working for one hour or so. I report tomorrow, if it is still working. Unfortunately all datas are lost. Victron should make it possible to do a backup.

I have identical problem.

Is the only solution to delete the system from VRM and complete reset?

Hi @Bert Hennephof,

No, that is not a recommended solution, and I think in most cases that will not even resolve the issue, even though it appeared to for Skykay.

Can you please post some more info to help diagnose it?

What is the VRM site url?
