Bonjour tout le monde,
Premier post sur ce forum, pour un premier problème ! 
Mon problème
C’est la toute première fois que j’installe HA.
J’ai suivi le Tuto du site HA : installation sur une Raspberry Pi 4, sur carte SD, flashée à l’aide de l’utilitaire Raspberry Pi, connexion ethernet direct sur ma box de mon FAI sans autre routeur interposé.
Au démarrage, j’ai pu accéder brièvement (de l’ordre de 5 min) à la page de HA, sur l’adresse classique homeassistant:8123. J’ai vu la barre de progression, 20 min ou plus pour l’installation, et des logs. J’ai eu la présence d’esprit d’en télécharger une copie (cf plus bas).
Au bout de 5 min sur cette page (sans avoir pu créer id et mot de passe donc, toujours en cours d’installation), je n’y ai plus eu accès, avec l’erreur ERR_CONNECTION_REFUSED. Cela fait maintenant 2h que je n’y accède pas.
Ce qui est étrange, c’est que j’accède parfaitement à l’observer sur homeassistant:4357, qui me note :
|Supervisor:|Connected|
|Supported:|Supported|
|Healthy:|Healthy|
Je n’ai rien en termes de paramétrage réseau entre temps.
Ce que j’ai essayé
J’ai bien sûr testé tout le troubleshoot de première intention :
- Accès sur {IP_HA}:8123 en identifiant son IP sur ma box,
- Accès en protocole http et https (des fois que ça change quelque chose),
- Accès avec le .local ou sans le .local,
- Accès via Chrome et Safari,
Rien n’y fait ! Je ne peux pas accéder à la page ! Le port 4357 par contre lui est toujours accessible.
Autre essai : HA répond bien au ping via le terminal sur mon Mac (ping de son IP).
J’ai aussi testé de réinstaller complètement l’OS en flashant de nouveau la carte SD, avec exactement le même soucis.
Enfin dernier détail : je n’ai pas d’écran avec un connecteur microHDMI sous la main pour aller voir directement sur la console ce qu’il se passe…
Des idées ?
Merci d’avance pour votre aide précieuse
