Error fetching victron data: Fetching registers failed every minute

[sylvainzabe]

Hello I have Home Assistant installed in a virtual machine under Proxmox wired by ethernet.
I have a Cerbo GX connected by Wifi.
Since few weeks I have an error every minutes : "Error fetching victron data: Fetching registers failed".
I tried to wire Cerbox GX by ethernet but no changes and a constant ping doesn't show a network issue, every pings are ok even during the error.
During this error Victron entities are reported as unavailable.

The error message :
"Cette erreur provient d'une intégration personnalisée

Enregistreur: custom_components.victron.coordinator
Source: helpers/update_coordinator.py:344
intégration: victron (documentation, problèmes)
S'est produit pour la première fois: 01:50:00 (37 occurrences)
Dernier enregistrement: 08:46:00

It seems, but I'm not 100% sure, that this errors started to occur when I changed my battery system, I have switched from Ni-Fe batteries to Pylontech batteries.

Screenshot of entities when I get the error :
