EVCC Add-on is running but shows that it is not

Hi

After starting the EVCC add-on the UI could not be opened. The message is shown:

Add-on is not running. Please start it first

But I can open the log and following text is shown:

Obviously the app was started correctly and is also running safely in the background, as I also have access to my inverter via the modbus in EVCC. Otherwise I could not see any data of the inverter in HA.
The whole problem only arose after the last upgrade to HA core 2023.4.4. With the upgrade, I could no longer start both evcc and the solar add-on (Hauwei). After a restore with the backup, the add-ons are running again but I can no longer operate EVCC.

Does anyone have an idea how I can solve this problem?

Problem solved… no idea why, but suddenly add on is reachable again.
