Login stuck with "Start over" button

[zabi94]

I installed the app on Fedora 40. When I try to log in the app won't proceed any further, it simply switches to a "Start over" button in the center of the login window as pictured.

Butler v1.2.0
HA served through Cloudflare reverse proxy from my home server (login through web page works fine)

Are you using some sort of multi-factor authentication?

[zabi94]

No, simple username and password login

Having the same issue with my external domain, which is proxied through caddy and cloudflare. It works when just using the local ip and port. Butler 1.3 on Arch, Home assistant 2024.6.2.

have you put a / after your fqdn?
I had this issue when accessing it through https://host.example.com , when appending the / to make it https://host.example.com/ it let me put in my 2FA and logged me in.
I hope this helps ^^
