Fully Kiosk - Cannot authenticate

Hello, I’m unsure where to ask this question as it is pretty specific. After upgrading a tablet, to a Lenovo M10, that my wife and I use for cooking, I’ve been unable to log in to Mealie.

I do have this self-hosted Mealie docker container exposed to the WWW through reverse proxy and all that, but for this instance, I am going straight to the http://local.ip.address:port. If I go to Mealie’s IP address through my phone, laptop, or even within the tablet itself by opening Chrome, I can log in to the “tablet” user, no problem.

The problem comes from when I try to access Mealie from Fully Kiosk Browser. My dashboard consists of a single webpage card that goes directly to Mealie’s IP address. When I open the dashboard, I can see Mealie, no problem, but when I try to log in, I can’t. If I look at Mealie’s log, I see this:

[INFO|httptools_impl|L483] 2026-01-04T12:26:55: 192.168.100.21:47450 - “POST /api/auth/token HTTP/1.1” 200
[INFO|httptools_impl|L483] 2026-01-04T12:26:55: 192.168.100.21:47450 - “GET /api/users/self HTTP/1.1” 401

I know the credentials are right, I can log in to this username from any other device and again, from the tablet itself, but outside of Fully Kiosk Browser. I’m at a loss, any ideas?
