After reboot HA, Tado failed to setup: Login failed for unknown reason with status code 403

[Kraganov]

The problem

After a reboot of HA, I suddenly got notified that the Tado integration failed to setup.
It showed a configure button to configure the fallback method, but this didn't change anything.
Tried to reconfigure by entering my password again, failed with "unexpected error"

When I check in the logs I first find this log:

2025-03-21 07:55:29.472 ERROR (MainThread) [homeassistant.util.logging] Exception in <function _register_repairs_platform at 0x7fd54ab43a60> when processing platform 'repairs': (, 'tado', <module 'homeassistant.components.tado.repairs' from '/usr/src/homeassistant/homeassistant/components/tado/repairs.py'>)

a bit further the following:
