This is a moved issue from Ferdinand99/home-assistant-newt-addon#3, as it affects the Pangolin authentication.

Describe the bug

After successfully installing the Home Assistant Newt Addon the HA instance is available through the specified domain in a Browser. But when trying to connect via android app to the ha instance an error message

Unable to connect to Home Assistant.

Retrying in 41 seconds...

under the URL https://my.domain.com/lovelace?external_auth=1 is interrupting the login process.
When disabling the Pangolin authentication the app authentication works, but not when enabled.

To Reproduce

Steps to reproduce the behavior:

Install Newt Addon on Home Assistant
Enable resource authentication in Pangolin
Try to log in via the Home Assistant Android app
Login with Pangolin authentication
Unable to connect

Expected behavior

The browser would backlink to the android app and successful log me in
