Like the title says. I can access my instance just fine through the mobile app, but as soon as I try to use the link that Nabu Casa provides me to access my instance through a browser (I tried Firefox, Brave, and Chrome), it shows a log message on my instance saying that there was an invalid login from localhost. It's generated by the homeassistant.components.http.ban module, and it's complaining about invalid auth.
I've used both the username and password for my instance and my nabu casa account with the same error, thinking there's something weird with it. I changed my password and relogged into the mobile app correctly, but through a browser it still says the same thing.
I'm at a loss as to why it's not working.
