### Expected Behavior
I'm running AdguardHome in Docker through UnRaid. Trying to load iframe through a docker front end organizer (DashAssistant) AdGuard Home UI set up as an iFrame panel. Acces through Chrome on Windows 10. The iFrame should load the site, allow login, and full access to the complete UI.

### Actual Behavior
Everything works correctly when HA is launched in a computer web browser. However, after attempting to log on, you are returned to the login screen. No message is generated saying invalid credentials, but if bad credentials are used, that message is displayed. This only happens in the iFrame configuration , going directly to the AdGuard Home web interface works as expected.
