Help with Long Lived Token Login

I’m trying to setup simple guest access to my Home Assistant instance for guest users in my house by simply scanning a QR code.

I user Meraki wireless and have the QR code configured to log the user onto my guest network and then direct users to a splash page which redirects them to my Home Assistant URL. I’ve appended the URL with the guest dashboard name and a long lived token associated with a limited guest account I’ve created.

Currently the QR code lands the user at the login page but the long lived token does not appear to be automatically logging the user in.

Any thoughts or tips as to why this might be?

Thanks!

So I am finding that Home Assistant won’t accept the LLT when simply presented as part of the URL and I can potentially use Nginix reverse proxy to inject the token.

Struggling to get this going also. Anyone able to help that has experience with using Nginx in such a way? I’ve attempted using the official Nginix Proxy Manager add on but keep getting errors. Wondering if maybe I need to set this up as a stand alone VM or Container in proxmox to intercept the inbound traffic. A bit out in front of my skis on this experience wise.
