addon crashes when LAN is down

[fmiermont]

          @fmartinou avec la dernière version ça ne semble pas vraiment résolu; J'ai mon routeur qui reboot toutes les semaines, HA est connecté dessus, donc le lien réseau tombe.

Et l'addon se retrouve alors planté, je dois le redémarrer. Les logs donnent ça :

J'imagine c'est que lié !

I seem to have the same error: addon crashes when network is down, but I've got a different log:

Oct 08 14:36:06 homeassistant addon_6b64d821_tydom2mqtt[467]: 2023-10-08 16:36:06,137 - asyncio          - ERROR   - Future exception was never retrieved

...
10 000 more or so identical lines

Then nothing more in the log, until I restart the addon.
