Cloud issue: state are not refresh after some time

[deblockt]

After 1 or 2 day, the vacuum state is not refreshed anymore.
I can see this exception on log:

Traceback (most recent call last):
  File "/config/custom_components/proscenic/vacuum_proscenic.py", line 195, in start_state_refresh_loop

When I try to start to clean, I have this error:
