So I've been having issues all day getting my yubikey to register to use webAuthn 2FA Authelia. Have to admit that I'm a bit of a novice to all this to it's very possible that I might have overlooked something obvious.

build with docker-compose and nginx proxy manager, the setup seems to work since when i go to sub.domain.com i get redirected to auth.domain.com where i manage to login and then get asked to setup my 2FA, i opt for webAutn with my key and i get the email. I use my keys pin and asked to touch the key. As soon as i touch the key, i get the message "Failed to register your device. The identity verification process might have timed out."

Regardless if i wait 30 sec or touch it within 1 sec i get the same message.

Tried turning on and off proxy at cloudflare, tried 4 different browsers. Also tried going to auth.domain.com and I'm asked for 2FA with same results.

I even tried changing from two_factor to instead use one_factor (just while trouble searching) but now it still asks me for setting up key?

Any help is much appreciated!
