Problem when enrolling my FIDO2 key

The manual install may give you more flexibility but as mentioned does have a bit more nuance to it.
With your current setup you may try to check out these posts in the community, as it may help.


EDIT: Checking further this may be something that is specific to the FIDO2 auth, as others have had a similar problem.

So hopefully double checking the settings can help, otherwise perhaps the manual install may be needed for your own nginx reverse proxy and webauthn to function.
