Netatmo OAuth authorization loop when adding integration (Home Assistant Cloud / Nabu Casa)

Hello,

I am trying to add my Netatmo Smart Outdoor Camera to Home Assistant using the official Netatmo integration.

My setup:

  • Home Assistant OS
  • Home Assistant Cloud (Nabu Casa)
  • Remote URL working correctly
  • Netatmo Smart Outdoor Camera
  • No existing Netatmo integration configured

Issue:

When I click "Add Integration" → Netatmo, Home Assistant displays:

"This step requires you to visit an external website to be completed."

Home Assistant then opens the following URL:

https://api.netatmo.com/oauth2/authorize

After logging into Netatmo and clicking "Allow" to authorize Home Assistant Cloud, I am redirected back to the same Netatmo authorization page instead of completing the setup.

This creates an infinite authorization loop.

What I have already tested:

  • Safari and Chrome
  • Home Assistant local URL
  • Home Assistant Nabu Casa remote URL
  • No third-party applications are listed in my Netatmo account
  • Remote access through Nabu Casa is working correctly
  • The integration no longer shows "already_in_progress"

OAuth request contains:

redirect_uri=Nabu Casa Account Link

The authorization appears to succeed, but the callback never completes and the integration is not created in Home Assistant.

Has anyone experienced this recently?

Is this a known issue between Netatmo OAuth and Home Assistant Cloud / Nabu Casa?

Any help would be appreciated.

Thank you.
