Viessmann ViCare - No data from Vitocal and Vitocharge

Since 01.011.2025 I do not get any data from the Vitocal and Vitocharge VX system in HA. I did still get data from the thermostats.

After removing and reinstalling the integration, I do not get any data anymore.

Can we assume, that this is a Viessmann issue? How can this be fixed?
