no more connection to PyViCare PT2 fuelcell

[SPITZGITHUB]

I got via Python values from the fuelcell for to controll the fuelcell since some years with and without connection. But since mid of may I have more problems.
I found a solution when I read the issue: pip install pyvicare' doesn't work anymore on Raspberry PI #311 and with the help form crazyfx1. Now it runs again but always in midnight the connection was lost for 1 oder 2 hours.

But since 08.06.2023 at 18:07 I lost the connection to PyViCare.
Here the script with runs years for to collect values from the fuelcell.

**import sys
import logging
from PyViCare.PyViCare import PyViCare

client_id = ""
email = ""
password = ""

vicare = PyViCare()
vicare.initWithCredentials(email, password, client_id, "token.save")
device = vicare.devices[0]
t = device.asFuelCell()
circuit = t.circuits[0] #select heating circuit
burner = t.getBurner(0)
Komma =";"
ZW = str(t.getDomesticHotWaterStorageTemperature())
Wert = ZW + Komma
ZW = str(t.getOutsideTemperature())
Wert = Wert + ZW + Komma
ZW = str(circuit.getSupplyTemperature())
Wert = Wert + ZW + Komma
ZW = str(t.getReturnTemperature())
Wert = Wert + ZW + Komma
ZW = str(t.getDomesticHotWaterDesiredTemperature())
Wert = Wert + ZW + Komma
ZW = str(t.getDomesticHotWaterConfiguredTemperature())
Wert = Wert + ZW + Komma
ZW = str(burner.getActive())
Wert = Wert + ZW + Komma
ZW = str(t.getOneTimeCharge())
Wert = Wert + ZW + Komma
ZW = str(circuit.getDesiredTemperatureForProgram("reduced"))
Wert = Wert + ZW + Komma
ZW = str(circuit.getDesiredTemperatureForProgram("normal"))
Wert = Wert + ZW + Komma
ZW = str(circuit.getDesiredTemperatureForProgram("comfort"))
Wert = Wert + ZW + Komma
ZW = circuit.getActiveProgram()
Wert = Wert + ZW + Komma
ZW = str(burner.getStarts())
Wert = Wert + ZW + Komma
ZW = str(burner.getHours())
Wert = Wert + ZW + Komma
ZW = str(t.getHydraulicSeparatorTemperature())
Wert = Wert + ZW + Komma
print(Wert)**

When I run this script I got the following errors:

I have deleted the token.save but no success.

Can you help me to reconnect to the fuelcell?
